Von Mises equivalent stress 193 Crack Arrest Modeling • Four point bending beam with a side crack ‐ Line pressure loads are applied • The model forms an asymmetric load pattern to crack where top part is subjected to compression and bottom part id under tension ‐ FCG is conducted ‐ Paris law with threshold is used ‐ CZM elements are automatically inserted at first substep and subsequent crack propagation substeps ‐ CZM elements are only to use for preventing crack surface penetration ‐ A small threshold value is used to prevent negative KI value used in the effective stress intensity factor range calculation Crack front evolution with SIF K I Four point bending specimen A B A B
