A Review of Damage, Void Evolution, and Fatigue Life Prediction Models

Abstract

This paper aims to provide an overall review of degradation, damage evolution and fatigue models in the literature of various engineering materials, mostly metals, and composites.

A thermomechanical constitutive model for investigating the fatigue behavior of Sn‐rich solder under thermal cycle loading

“…The fatigue failure of solder joint under TCL is the process of cracks initiation and propagation, which is induced by the accumulation of strain‐based variables or the inelastic energy 48–52 . Chen and Pang 49 developed a strain‐based fatigue life model for solder joint under TCL, which is defined as follows: where is the fatigue lifetime, is the increment of strain‐based variables under one cycle, and and are material parameters with positive values.…”

Failure behaviors and processing maps with failure domains for hot compression of a powder metallurgy Ni-based superalloy

“…The GTN model has been also widely applied or extended for modeling the ductile fracture of other metals such as steel [16,17], Al [18][19][20], Mg [21], and under a broad range of stress states [22][23][24]. More about the GTN model and its modifications can be referred to from a recent review by Lee and Basaran [25]. However, relatively few studies have been reported to probe the failure behaviors and thresholds of P/M superalloys under different TMP parameters by employing FEA with the GTN damage model.…”

Various parameters of the multiaxial variable amplitude loading and their effect on fatigue life and fatigue life computation

“…It is no wonder that there are voices stating that the common fatigue life estimation procedures „ … primarily rely on the test data curve to fit the empirical void/damage evolution function…These empirical models are popular for engineering applications due to their simplicity . Still , the identification of parameters is costly , time‐consuming , and lacks any scientific basis due to a lack of physical and mathematical foundations” 8 and that a completely different solution must be found. If the common procedure of fatigue life estimation is assessed, the multitude of various effects, intertwined but solved separately, is really striking.…”
