Abstract
The calculation method of fracture parameter is introduced in this paper. By using the project software ANSYS to simulate two kinds of two-dimensional finite element model, the model I crack tip fracture parameters: K1, K2, G are analyzed and calculated for different crack length, different material parameters and different loads. After comparing the crack tip stress intensity factor and the energy release rate with each factor, we find that the fracture parameters are related to the crack length and loads, but not the material parameters. The results may provide the guidance for calculation of fracture parameter base on ANSYS.
