A Novel Methodology for Calculating Crack Opening Stress under Tension-Compression Cyclic Load

<div>The criterion of crack opening stress. The difference of crack opening stress criterion lies in monitoring different nodes on the crack surface. The CT specimen is shown in the form of line with dots, and the nodes monitored by different criteria are distinguished by node color.</div>
