| Abstract: | A single specimen COD resistance curve test technique based on unloading compliance method using IBM-PC Computer for data acquisition and processing is studied in this paper. The revision of crack length is systematically studied. A set of applicable softwares is developed and a criterion of COD resistance curve is proposed for homogeneous and heterogeneous materials. |
