Abstract

The presented review consists of two parts. The first one is devoted to research generalizing the classical Prandtl problem in the case of taking into account the inertia of the convergence of rigid plates and dynamic effects occurring in a thin perfect rigid plastic layer. The second part examines the work related to the formation and development of the neck in plastic materials under quasi-static and dynamic loading. In particular, attention is paid to thin solids with a perturbed boundary shape, which have technological significance. The presence of a small geometric parameter allows using the asymptotic methods.

薄型完全刚塑性体的流动:动力模式和颈缩
本报告由两部分组成。第一部分将经典普朗特问题推广到考虑刚性板的收敛惯性和薄的完美刚性塑性层中发生的动力效应的情况。第二部分研究了在准静态和动态载荷下塑性材料颈部形成和发展的相关工作。特别关注具有微扰边界形状的薄固体,具有重要的技术意义。小几何参数的存在允许使用渐近方法。
