Don’t hesitate to ask any questions you might have about the explanations presented in this video using the comments below. We try to answer all questions regarding the video details in the comments below.

In many engineering problems, material goes beyond its ultimate stress. So the material enters its damage region. At this case, damage must be introduced to the mechanical behavior of the material.
There are two different methods for damage analysis in FE models:
1) Fracture Mechanics(XFEM, CZM, VCCT)
2) Continuum Damage Mechanics(Ductile damage, Johnson-Cook damage, Shear damage, CDP)
In this video, damage analysis based on CDM is explained. explanations are related to tensile test. The Force-Displacement curve is discussed too.
damage analysis concepts including damage initiation point and damage propagation are explained in detail.
