Creep and fatigue slow crack propagation of engineering thermoplastics display continuous or discontinuous manner depending on the test condition. It could be simulated accurately by use of crack layer theory with theoretical backgrounds. But many input parameters complexify the use of CL theory. Thus the investigation on the effect of material parameters on the CL growth is necessary for the comprehensive understanding. In this paper, a parametric study of CL growth simulation of single edge notched tension specimen in creep condition was performed. Several material parameters were varied so that the effect of input parameters on the CL growth behavior could be understood. Total lifetime is used to figure out the effect of the parameters quantitatively. This study would be beneficial to understand the effect of material parameters on the slow crack growth behavior of high density polyethylene.
