摘要
A two parameter fracture model is proposed to include nonlinear slow crack growth. Critical stress intensity factor is calculated at the tip of the effective crack. The critical effective crack extension is dictated by the elastic critical crack tip opening displacement. Tests on notched beam specimens showed that the proposed fracture criteria to be size independent. The proposed model can be used to calculate the maximum load (for Mode I failure) of a structure of an arbitrary geometry. The validity of the model is demonstrated by an accurate simulation of the experimentally observed results of tension and beam tests.
