“…This model is based upon the fact that the surface layer is much softer than the bulk material or yield stress of larger surface grains is significantly lower than of the bulk material. A steep yield strength gradient extending a fraction of the millimeter has been reported in surface layer of an aluminum alloy (Morris et al., 1987). In the surface layer model (Kujawski and Ellyin, 1990), the surface thickness is subdivided into series of strips whose thickness is equal to the size of process zone, δ*.…”

A small Mode I crack, normal to interfaces between elasticity and plasticity mismatched material layers, in a residually stressed aluminum–fiber laminate (Glare) is modeled under monotonic and cyclic loads. An analytical model is presented in small scale yielding or K-dominant regime that quantifies the effect of property mismatched interfaces over the crack tip in the laminate by determining energy release rate and stress intensity parameter. Cracked laminate is also modeled by finite element method. Values of energy release rate and strain energy density are obtained over cyclic paths far away from the crack tip, around the influencing interfaces, and in the vicinity of the crack tip. Numerical results are found to be close to theoretical estimations. Re-distribution of stress state in un-identical material layers during crack growth, resulting in different energy release rates of the crack in the laminate vis-a-vis those of the crack in similarly stressed homogeneous aluminum, is well substantiated. Methodology to incorporate the surface and material micro-structural effects over the crack is also proposed.

We present a review of the determination of residual stresses in materials and components of industrial interest by using the non-destructive technique of neutron diffraction. The fundamental aspects are discussed, together with a brief description of the experimental facilities. Several experimental results are then reported, particularly concerning applications to materials and components for power plants (CrMo steel, AISI304 stainless steel and 2.25Cr1Mo ferritic steel), aerospace and automotive technology (Al alloys, metal matrix composites, nickel superalloy gas-turbine components) and fusion-reactor technology (AISI316L for the first wall). A few thermomechanical treatments are considered, such as welding, cold-expanded holes, thermoelastic coupling and thermal and mechanical fatigue. Moreover, a few applications to general industrial problems are shown, namely brazed ceramic-steel components, coatings and fatigue-cracked samples. In some cases, experimental results are compared with numerical models or results from x-ray diffraction measurements.
