Abstract
The mesh-characteristic method is used to study some two-dimensional dynamic problems of the mechanics of a deformable rigid body, notably, the problem of small elastic and elastic-plastic deformations of a plate or shell of finite thickness (including the case when thermal effects are present), and the problem of the high-speed impact of absolutely rigid strikers with a plate of finite thickness. The influence of the choice of coordinate system (Lagrangian, moving Euler, or a combination of these) in problems with large deformations is studied.
