Direction of crack propagation in a complete contact fretting-fatigue problem
E Giner, M Sabsabi, JJ Ródenas… - International Journal of …, 2014 - Elsevier
In this work, the orientation and propagation of a crack in a fretting fatigue problem is
analyzed numerically and correlated experimentally. The analysis is performed using a 2D
model of a complete-contact fretting problem, consisting of two square indenters pressed
onto a specimen subjected to cyclic fatigue. For the simulation, we use the extended finite
element method (X-FEM), allowing for crack face contact during the corresponding parts of
the fatigue cycle. The problem is highly non-linear and non-proportional and an orientation …
