Abstract

Plastics used for structural applications are often subjected to creep loading and component lifetime will be limited by crack propagation. A finite element model of crack growth in plastics subjected to creep loading is developed. The model is comprised of a viscoplastic model of the bulk material and a cohesive zone model for tracking crack growth. Model parameters are found by curve fit to experimental data for polyethylene sheet samples. Model predictions for creep behavior and time to failure under creep loading conditions are compared to published data for HDPE. The model predicts the trends observed in the published data.
