摘要
本文对工业和科研部门等领域常用的几种塑料进行了力学破坏行为的探讨.并通过试验说明了它们在机械性能上的差异及在工程中正确掌握塑料的机械性能,精确有效地设计塑料制品,具有重要意义。最后通过与传统的工程材料低碳钢进行了比较,讨论了该两种工程材料力学性质上的差异及实验方法上的不同。
This paper makes an approach to the mechanical destruction action on the several common plastics used in industries and sci entific research realm,and gives an exposition of their differ ences in mechanical properties through experimentation.This is of obviously great significance in the correct mastery of mechan ical property and in the precise and effective design of plastic products. In comparing plastic products with the traditionally used low- carbon steel of engineering,materials,this paper also discusses the differences i mechanical property between these two kinds of engincering materials,and the distinctions in their experi mental methods.
