FRACTURE SIMULATIONS OF PARTICULATE PIEZOELECTRIC COMPOSITES USING THE XFEM

摘要：

This paper investigates the influence of a piezoelectric (PE) particle pair on the crack-tip parameters.The I-integral is employed to solve the crack-tip stress intensity factors (SIFs) and electric displacement intensity factors (EDIFs) of a PE/dielectric material.The I-integral can decouple mixed-mode SIFs and EDIFs,and moreover,it is domain-independent for material interfaces,which greatly facilitate the extraction of the crack-tip field intensity factors for PE particulate composites by adopting an integral domain with arbitrary interfaces.Finally,a cracked dielectric plate reinforced by a pair of PE particles is studied to investigate the influences of the particle pair on the SIFs and EDIFs.
