Resumo
Crack propagation simulation began with the development of the finite element method; the
analyses were conducted to obtain a basic understanding of the crack growth. Today structural and materials
engineers develop structures and materials properties using this technique as criterion design. The aim of this
paper is to verify the effect of different crack propagation rates in determination of crack opening and closing
stress of an ASTM specimen under a standard suspension spectrum loading from FD&E SAE Keyhole
Specimen Test Load Histories by finite element analysis. The crack propagation simulation was based on release
nodes at the minimum loads to minimize convergence problems. To understand the crack propagation
processes under variable amplitude loading, retardation effects are discussed.
