The evaluation of energy release rate with angle is still a challenging task in metal crack propagation analysis, especially for the mixed Mode I-II-III loading situation. In this paper, the energy release rate associated with stress intensity factor

The physical interpretation of the J integral (i.e., J1 integral) is clear. J1 integral is the energy release rate associated with crack extension (i.e., translation of the crack in the x1 direction). However, the physical interpretation of the J2 in

As a fatigue crack grows, its shape changes. Conventional method for predicting the shape change typically requires the computation of several hundred increments to get accurate results. In this paper, a new finite element simulation technique that u

As a fatigue crack grows, its shape changes. The shape of the growing crack can be affected by the initial crack shape, the load type and the fatigue crack growth rate of the material. Existing methods to predict the shape of the growing crack includ

Finite element simulation of stable fatigue crack growth using critical crack tip opening displacement (CTOD) was done. In the preliminary finite element simulation without crack growth, the critical CTOD was determined by monitoring the ratio betwee

The catalytic converters for automobile exhaust systems are manufactured by inserting a mat-wrapped substrate into a stainless steel can. A residual pressure that is too high will initiate a fracture in the substrate. In contrast, a residual pressure
