Hello. I am trying to implement delamination, and I have a question.
The shape of the model to be analyzed has a hexahedral shape by bonding two flat elastomers, and a rectangular hole is formed inside. As a boundary condition, when the stress caused by the pressure applied to the inner hole exceeds the elastic properties of the elastomer, the stress between the bonded interfaces and the separation that occurs are realized. Also, there is no initial crack inside the model.
Looking at the existing example files (Mixed-Mode Debonding of a Laminated Composite) that implemented delamination, in order to apply decohesion in the contact condition,
First, consideration of various physical properties (tensile strength, shear strength, tensile energy release rate, shear energy release rate) with a material approach
Second, it can be confirmed that the initial crack is considered with a kinematic approach.
Please comment on the physical assumptions (initial crack) that must be considered essential for the analysis we want or the additional considerations.
