The Error Analysis of Material Elastic Modulus and Strength in Similar Material

Model tests are widely used in engineering, and in similar material model test the basic similarity relation must be considered reasonable. To improve the accuracy of the similar material simulation experiment, ten pairs of tests are designed to compare the elastic modulus. What´s more, according to the research status and characteristics of similar material test, analysing of source of error from block maintenance and block test of similar materials contribute to improve the accuracy of similar material simulation test.
