Abstract

A number of works have been reported in the literature up to present on finite element ductile failure analysis. Depending on the model employed for damage simulating, the Gurson-Tvergaard-Needleman model can be broadly used. That model is using a micro-mechanical model for ductile fracture, incorporating void nucleation, growth and coalescence. As many researchers have already published a number of papers using these methods, applicability and validity of these methods have been well discussed in the literature. In this paper, to simulate long, stable ductile tearing in large-scale pipes using finite element analysis by GTN model. The GTN damage model and associate parameters are determined from fracture toughness test.
