An Information Theoretic Argument on the Form of Damage Accumulation in Solids

Effect of Static and Dynamic Aging on Fatigue Behavior of Sn3.0Ag0.5Cu Solder Alloy

“…The Maximum Entropy Fracture Model (MEFM) was developed by Bhate et al [12]. It was inspired by two experimental observations: (1) the process of crack propagation is thermodynamically irreversible and dissipative, and (2) fracture intrinsically has lengthscale, timescale and/or spatial hierarchy, which is affected by microstructural states.…”

“…The Maximum Entropy Fracture Model was proposed as a geometry-independent, non-empirical fracture model by Bhate et al [12]. The key concepts behind the development of MEFM were reviewed.…”

“…This is an irreversible process with energy loss when new surfaces are created. Bhate et al [12] derived a relationship between entropic dissipation and inelastic dissipation with equilibrium thermodynamics and J2 plasticity theory.…”

“…Based on Jaynes' work [30], Bhate et al [12] argued that by maximizing the information entropy, the relationship between energy measure ψ and the probability p i could be determined. The expression relating probability of event x i to the energy measure ψ i is as follows:…”

“…The Maximum Entropy Fracture Model (MEFM) was developed by Bhate et al [12] based on information theory and statistical thermodynamics. The author argued that with maximum entropy principle, the reliability prediction becomes possible even when microstructural uncertainties exist.…”
