Abstract
Stiffness often becomes an issue when metallic materials are replaced with engineering plastics for the use of structural components. Fracture behaviors of the Liquid Crystalline Polymer (LCP) which have been widely adopted in electronic
products are investigated in the current study. Finite element analysis is carried out in conjunction with a self-coded user subroutine VUMAT accounting for the mechanical response of the plastic materials. Various parameters required for a constitutive model with rate-dependency are first evaluated using experiments for a plastic sample subjected to the uniaxial compression condition. Failure assessments of a plastic housing of a memory connector under application conditions are conducted, and the simulated crack appearing in the housing matches rather well with the corresponding experimental observation.
