Abstract

An explanation for a feature found in several experiments in the general picture of the destruction of non-brittle polymers under the influence of a shock wave initiated by a powerful electron beam is proposed. The distance of the cracking region from the surface of the material affected by the beam to a finite length in depth is associated with the three-dimensional nature of the propagation of elastic waves. The universality of the effect is demonstrated by the simplest isotropic model, which shows that large tensile stresses are effectively generated inside the target at its sufficiently large transverse and longitudinal size, even without taking into account nonlinear and shear processes.

论弹性聚合物材料在电子束作用下的破坏

摘要对在强电子束引发的冲击波影响下非脆性聚合物破坏的一般图景中发现的几个实验特征提出了解释。开裂区域从受电子束影响的材料表面到有限深度的距离与弹性波传播的三维性质有关。最简单的各向同性模型证明了这一效应的普遍性，该模型表明，即使不考虑非线性和剪切过程，在横向和纵向尺寸足够大的靶内部也能有效地产生较大的拉伸应力。

期刊介绍： Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
