Abstract
A structural analysis software referred to as V-X3D, which is based on the extended finite element method (X-FEM) using the VCAD framework provided by RIKEN, was developed and applied to perform a crack propagation analysis. In the method utilized for the developed software, crack geometry is expressed with triangular patches explicitly for finite element models and elastostatic analyses are performed by X-FEM. In crack propagation analyses, crack geometry is updated for adding triangular patches after each loading cycles using Paris' law, where crack growth rate is related with range of stress intensity factor (SIF) around a crack tip. SIF is evaluated by energy release rate, which is calculated by the domain integral method. As numerical examples crack propagation analyses for a plate with a circular crack under tension loading and a round steel bar with a straight notch under four points bending loading were performed by V-X3D. The validity was examined through comparisons with numerical results by another method and experiment results.
