5. The initial and boundary conditions of the sample compressed with rigid plate

The initial and boundary conditions were defined as in the experiment. They can be summarized in the following points:


A solution of contact (Eq. (22)) between two or more parts in the explicit method consists in the fact that the surface of the acting component, so-called Slave Area (the plate), pushes on the surface of the second part, so-called Master Area (the sample), wherein the contact is calculated between the nodes of two bodies which are in the conjunction [23] (Figure 22).
