Three coating materials are investigated: DLC, CrN and Al2O3.
Besides, the crack growth criteria for ductile materials are not well developed yet.
In general, there are four models of materials’ fracture toughness based on the material thickness and the fracture mode.

Flexible Rolling Theory Flexible rolling method is a special rolling method. work rolls should choose small diameter and high-strength materials.
When the sheet material has a larger Gaussian curvature, the plate material has significant deformation.

Introduction It is of great importance to characterize the properties of viscoelastic materials in order to use them in engineering applications[1].
On traditional test of dynamic response of viscoelastic materials, if we used the strain of somewhere in the bar instead of that contacted with the surface of test specimen and adopted the method of two-wave or three-wave to deal with formulas of stress, strain and strain-rate, it would be bound to bring deviation to the experimental result due to the effect of attenuation and dispersion.
