Edit: Just noticed that the previous version has been Wavelab LE 7 - is your upgrade valid for the LE version of the application? Somehow I would think that Wavelab 10 elements upgrade is only valid for Wavelab 7 Elements.
Plot: A downtrodden college football team discovers a defensive superstar in its water boy. Stars: Adam Sandler, Henry Winkler and Kathy Bates. Notable cameos: The Big Show and Lawrence Taylor ("don't smoke crack"). What went right: I probably liked this movie more than most. And I still liked to drop the term "foosball" when talking about football, so it does have some quotable lines. What might only interest me: This is the first of many appearances of Rob Schneider in this list. Spoiler alert: Of course, Bobby Boucher's team wins. But Dan Fouts actually makes me laugh during his cameo.

Statistically based phenomenology of mesodefects allowed the interpretation of damage kinetics as the scaling transitions in defect ensembles and the explanation of limited steady-state crack velocity, transition to the branching regime, scaling aspects of dynamic and fatigue failure. Qualitative different nonlinearity for damage kinetic equation was established for the slip bands and microcrack controlled stages of fatigue failure. This allows the original interpretation of the 4th Paris law in the terms of scaling universality and the explanation of the crack closure effect as the consequence of the anomalous energy absorbtion at the crack tip zone during scaling transitions in mesodefects ensemble. Presented results reflect the long-term collaboration of research teams of the Laboratory of Physical Foundation of Strength of the Institute of Continuous Media Mechanics of RAS (Russia) and LAMEFIP ENSAM of the Bordeaux University (France).
The recent experimental study of dynamic crack propagation revealed the limiting steady state crack velocity, a dynamical instability to microbranching [1, 2], the formation ofnon-smooth fracture surface [3], and the sudden variation of fracture energy (dissipative losses) with a crack velocity [4]. This renewed interest was the motivation to study the interaction of mesodefects at the crack tip area (process zone) with a moving crack. The still open problem in the crack evolution is the condition of crack arrest that is related to the question whether a crack velocity smoothly approaches to zero as the loads is decreased from large values to the Griffith point [5]. There is also problem at the low end of crack velocity. How a crack that is initially at rest might achieve its steady-state.
The increasing interest is observed in the use of mesoscopic approach in the condition of cyclic loading of the high-strength brittle materials (ceramics, intermetalics) and traditional materials (metals, alloys) after the structure reforming due to the compacting of metal (alloy) powder or granules. Such materials have the improved specific strength at high temperatures and simultaneously reveal the pronounced lack of damage tolerance due to the distinct features of fatigue crack propagation related to the nonlinear behavior of defects. Fatigue damage is one of the major life limiting factors for most structural components subjected to variable loading during service [6, 7]. The natural tendency in the
Several types of fatigue damage have been identified in [8]: persistent slip bands (PSB); roughness profile of extrusion; microcracks formed at the interfaces between PSB and matrix, in the valleys of surface roughness of PSB surface profile; fatigue damage at grain boundaries. Most
of the damage causing defects range from 1 ^m to 1 mm which is below the in-service non-destructive evaluation (NDE limit 1 mm) inspection limit. It is generally observed that a component in service seems to spend about 80 % of its life-time in the region of short crack growth. Hence studies on nucleation and growth kinetics of these cracks become a necessary part of assessing the total life.
which coincides with the deformation induced by defects. The dimension analysis of damage accumulation and the hypothesis of statistical self-similarity were used for the description of the statistics of nucleation and growth of defects (microshears, microcracks) responsible for the damage-fai-lure transition. Self-similarity of fatigue damage accumulation means [9] that only mean size of defects increases in time, but the distribution function of defects is invariant in the terms of some dimensionless variables. The established fact of self-similarity allowed one to propose the quantitative relationships between characteristic variables in some fatigue laws and interpretation of power-type constitutive equations [10]. Self-similar features take the place when the dominant mechanism subjects the evolution of complex system. As it was shown in [11] the self-similar mechanism of fatigue crack can be linked with the self-similar morphology of fatigue bands with the number of cycle.
[12]the distribution function of defects can be represented in the form of stationary solution of the Fokker-Plank equation W = Z_1 exp(- E/Q), where Z is the normalization constant. The key question in such formulation is the definition of the energy of defect in the condition of the interaction of defect with the external stress and structural stress induced by the surrounding defects and the dispersion properties of the system given by the value of Q. According to the presentation of the microcracks (microshears) as the
Direct experimental study of crack dynamics in the preloaded PMMA plane specimen was carried out with the usage of a high speed digital camera Remix REM 100-8 (time lag between pictures 10 ^s) coupled with photoelasticity method, Fig. 4 [16].
The pictures of stress distribution at the crack tip is shown in Fig. 5 for slow (V VC) cracks. The experiment revealed that the pass of the critical velocity VC is accompanied by the appearance of a stress wave pattern produced by the daughter crack growth in the process zone. Independent estimation of critical velocity from the direct measurement of crack tip coordinates and from pronounced stress wave Doppler pattern gives a correspondence with the Fineberg data (VC - 0.4VR) [17].
The generation of the collective modes in defect ensemble localized on spatial scales allows the description of the appearance of dislocation substructures (PSBs, crack hotspots) in some universal way. The scales of localization of these modes (Lw in the case of the orientation transition and LC in the case of the crack hotspot) play the role of the current scaling parameters in the definition of the current value of 8- (Lw/LS)3 for the PSBs transition type and 8 = (LC/LS)3 for the crack hotspots transition. Here LS is the characteristic spacing between mentioned mesodefect substructures.
-1 -10- s. This result leads also to the explanation of linear dependence of the branch length on the crack velocity [26]. Actually, since the failure time for V > VC is approximately constant (tf - tc - 1 jws), there is a unique way to increase the crack velocity to extend the size of the process zone. The crack velocity V is linked with the size of the process zone LPZ by the ratio V = LPZ/1c.
Since the branch length is limited by the size of the process zone, we obtain the linear dependence of branch length on the crack velocity. This fact explains the sharp dependence (quadratic law) of the energy dissipation on the crack velocity established in [4]. In our experiments the dependence of the density of the localized damage zone on the stress was observed (Fig. 7).
Fracture surface analysis revealed the correspondence of the sharp change of the crack dynamics for the velocities VC and VB, and the fractographic pattern. The fracto-graphic image of the fracture surface was studied in the velocity range V 300-800 m/s when different regimes of the crack propagation were observed.
The first regime V 220-300 m/s is characterized by the mirror surface pattern (Fig. 8). The increase of the crack velocity in this range leads to characteristic pattern on the mirror surface in the form of the so-called conic markings [18, 19]. The conic markings are the traces of the junctions of the main crack and the damage localization zones that nucleate in the process zone. These data reflect the influence of the damage kinetics on the characteristic size of above mentioned failure structures on the surface.
The analysis of the roughness data in the term of the roughness exponent showed the dependence of the scaling properties on the regime of the crack propagation. However, the group of specimens was found with the exponent Z 0.8. This fact allowed us to assume the existence of the regime of crack propagation with universal scaling index close to Z 0.8. The existence of different scaling indexes for other regimes of crack propagation reflects the variety of the behavior of investigated nonlinear system. As it was shown, the crack dynamics in quasi-brittle materials is subject to two attractors. The first attractor is given by the intermediate asymptotic solution of the stress distribution at the crack tip. The self-similar solution (9) describes the blow-up damage kinetics on the set of spatial scales and determines the properties of the second attractor. This attractor controls the system behavior for V > VB when there is a range of angles with a > ac. The universality of the roughness index can be considered also as the property of this attractor. In the transient regime VB > V > VC the influence of two attractors can appear. This reason can be considered as a mechanism of the roughness index dispersion on the scale r > r0. The scaling properties of failure were studied also under the recording stress dynamics using the polarization scheme coupled with the laser system. The stress temporal
history was measured in the marked point deviated from the main crack path on the fixed (4 mm) distance. This allowed the investigation of the correlation property of system using the stress phase portrait a a for slow and fast cracks (Figs. 10, 11). These portraits display the periodic stress dynamics (Fig. 11) that in the correspondence with the local ellipticity of Eq. (8) for a 2ff7e9595c
