Abstract EN
Based on the finite element software ABAQUS and graded element method, we developed a dummy node fracture element, wrote the user subroutines UMAT and UEL, and solved the energy release rate component of functionally graded material (FGM) plates with cracks.
An interface element tailored for the virtual crack closure technique (VCCT) was applied.
Fixed cracks and moving cracks under dynamic loads were simulated.
The results were compared to other VCCT-based analyses.
With the implementation of a crack speed function within the element, it can be easily expanded to the cases of varying crack velocities, without convergence difficulty for all cases.
Neither singular element nor collapsed element was required.
Therefore, due to its simplicity, the VCCT interface element is a potential tool for engineers to conduct dynamic fracture analysis in conjunction with commercial finite element analysis codes.
