Abstract
A numerical model for simulating fatigue creep crack growth in a specimen made of a visco-elasto-plastic material, such as sand-asphalt, is presented. The analysis uses the finiteelement method and is based on an unzipping procedure for crack extension, employing a critical octahedral shear strain as the fracture criterion. Furthermore the comprehensive visco-elasto-plastic material law is implemented in strain evaluation by the quasi-elastic approach. Following a detailed presentation and verification of the various assumptions involved in the model, the simulation's algorithm is described. The experimental validation of the model as well as its application to several cases are presented in Part II of this paper.
