工程陶瓷的抗弯强度测试及其误差分析

Testing and Error Analysis for flexural Strength of High Performance Ceramics

工程陶瓷抗弯强度测试过程中的误差分为两个方面:内部误差和外部误差。与简单梁理论不相符合带来的误差为内部误差,而由加载等因素引起的误差为外部误差。尽量减小或消除各因素带来的误差,有利于精确确定材料的抗弯强度。

The errors during the testing for flexural strength of high performance ceramics fall into two elasses: internal errors and external errors. Those that don't conform to simple beam theory are cal- led internal errors, and those arising from loading factors are called external errors. Minimizing or eliminating errors is fevourable to determine the fiexural strength accurately.
