有限载荷下单试样裂纹长度的卸载柔度法测量

The Measurement of Current Crack Length for Single Specimen at Limit with Unloading Compliance Method

采用句载乘度法，使用微机对试样裂纹在有限载荷下，缓慢持续扩展时裂纹的瞬时长度值进行计算，形成一套可供应用的软件．

In this peper,Partial unloading compliance method using micro-computer for data acquisition and Processing is studied to calculate current crack length until crack grows to wide range in a single three point bend specimen.A set of aPPlicable software is developed and the results make clear that the method is a simple and economic one.
