A global/local model reduction approach dedicated to 3D fatigue crack growth with crack closure effect

open access: yesIOP Conference Series: Materials Science and Engineering, 2010
It has been known for decades that fatigue crack propagation in elastic-plastic media is very sensitive to load history since the nonlinear behavior of the material can have a great influence on propagation rates. However, raw computations of millions of nonlinear fatigue cycles on tridimensional structures would lead to prohibitive calculation times ...
