A model for the prediction of growth rates of fatigue cracks in aluminium alloys is presented. The model is based on an approximate description of the crack closure behavior and can be used to predict effects of crack growth acceleration and retardat

Nowadays, application of the strip-yield model for computation of crack opening load levels is well known. In this paper the incremental formulation of a fatigue crack growth law is used to demonstrate the role of the crack opening load level in time

By finite element elastic-plastic analysis it has been possible to obtain detailed information on the deformation process in the vicinity of a growing crack in sheet metal. It is found that the crack grows when the value of the crack tip opening angl

The purpose of the present investigation was to design a simple specimen for which the stress intensity factor ( K ) is constant for a substantial range of the crack length. Moreover the crack growth direction should be stable without the necessity o

Publisher Summary This chapter presents the contribution to the analysis of quasi static crack growth in sheet materials. The finite element method (FEM) is used to show the phenomenon of slow stable crack growth. In this way detailed information is
