A probabilistic model to predict the formation and propagation of crack networks in thermal fatigue

摘要: A probabilistic model is presented to predict the formation and propagation of crack networks in thermal fatigue. It based on a random distribution sites where cracks initiate shielding phenomenon corresponding relaxed stress field created around cracks. Currently, considers only heterogeneous uniaxial loading even if fatigue multiaxial. However, first simulations mechanical representative gradient that appears shocks are qualitative agreement with experimental results. The larger amplitude, denser network smaller sizes.
