Cracking material
WebMultiple cracks usually initiate in the weld joints, because the weld butt and fillet contain heterogeneous microstructures, leading to high residual stresses at weld toes [1,2,3].Due … WebStress corrosion cracking (SCC) is the cracking induced from the combined influence of tensile stress and a corrosive environment. The impact of SCC on a material usually falls between dry cracking and the fatigue threshold of that material. The required tensile stresses may be in the form of directly applied stresses or in the form of residual ...

WebSep 15, 2024 · Figure 1: Examples of typical cracks caused by improper process recipes or inductor designs. Cracking and fractures can be classified in different ways, including ductile and brittle fractures, environmentally affected crack initiation, fatigue fractures, delayed crack initiation, and others. WebFatigue cracking results from cyclic stresses that are below the ultimate tensile stress, or even the yield stress of the material. The name “fatigue” is based on the concept that a material becomes “tired” and fails at a stress level below the nominal strength of …
