crack tip stress
1stress intensity factor — a scale factor to define the magnitude of the crack tip stress field; the functionality depends on the configuration of the cracked component and the manner in which the loads are applied …
2Stress intensity factor — Stress Intensity Factor, K, is used in fracture mechanics to more accurately predict the stress state ( stress intensity ) near the tip of a crack caused by a remote load or residual stresses.It is a theoretical construct applicable to a… …
3Stress corrosion cracking — (SCC) is the unexpected sudden failure of normally ductile metals or tough thermoplastics subjected to a tensile stress in a corrosive environment, especially at elevated temperature (in the case of metals). SCC is highly chemically specific in… …
4Stress concentration — A stress concentration (often called stress raisers or stress risers) is a location in an object where stress is concentrated. An object is strongest when force is evenly distributed over its area, so a reduction in area, e.g. caused by a crack,… …
5Fracture toughening mechanisms — In materials science, fracture toughening mechanisms are processes that increase energy absorption during fracture, resulting in higher fracture toughness.Intrinsic toughening mechanismsIntrinsic toughening mechanisms involve a fundamental change …
