THE PROBLEM OF A LINER TAPE FAILING ONTO AN INCLINED SUPPORT

The problem of numerical simulation of the contact interaction of a metal tape moving at a speed of about 0.5 km/s with a fixed inclined support for a time of about 100 𝜇s is considered. A two-dimensional approximation was used; an elastoplastic body model for large deformations was used to describe the tape and support. To take into account the boundary conditions on contacting surfaces, an iterative algorithm related to Neumann–Dirichlet type methods was used in the calculations. The finite element method is used for spatial discretization. The calculation results are presented. A number of model one-dimensional problems are considered, which make it possible to qualitatively evaluate the results obtained in the two-dimensional case.
