WebApr 5, 2024 · Smart materials and structures can offer some advantages for stress analysis of crack growth, such as self-healing, self-monitoring, self-diagnosis, and self-optimization. WebThe short crack growth based predictions provide more realistic estimates of the fatigue strengths than the predictions based on the local surface stresses. The latter are clearly highly pessimistic for the sharper notches. When based on the estimated average flake size, the short crack predictions lie within all the failure points for this ...
WebThe smart crack growth analysis tool uses the crack front in the pre-meshed crack approach, and the stress intensity factor is the failure criteria.
