岩土材料真实应力—应变试验关系

Experimental relationship between authentic stress and strain of rocklike material

本文就岩石、混凝土试件在普通压缩试验条件下，如何消除截面和端部效应的影响以及真实应力—应变试验曲线的作图方法进行了分析和探讨。

Abstract The paper introduces a method achieving authentic stress-strain testcurves of rocklike materials under normal compression test conditions. Thismethod enables to clear up the influences of cross section and both ends ofspacemen on the stress-strain characteristics of the sample.
