摘要

本文介绍了在初始温度为 20-185°C 的范围内，最大压缩应力为 0.6 GPa 时聚碳酸酯的剥落强度测量结果。结果发现，当聚碳酸酯达到玻璃转化温度时，其剥落强度会明显下降。塑性压缩波中的应变率取决于单次和逐步冲击压缩下的最大应力。构建了不同温度下最大冲击压缩应力（最大 0.8 GPa）范围内冲击波速度 Us-mass 速度的相关性。

Spall Strength of Polycarbonate at a Temperature of 20–185°C

The results of the measurements of spall strength of polycarbonate at a maximum compression stress of 0.6 GPa in the initial temperature range of 20–185°C are presented. It has been found a significant decrease in the spall strength when the polycarbonate reached the glass transition temperature. The strain rates in the plastic compression wave are determined depending on the maximum stress under single and stepwise shock compression. The dependences of the shock wave velocity U_s—mass velocity up in the range of maximum shock compression stresses up to 0.8 GPa at different temperatures are constructed.

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.
