EK401
The danger of brittle fracture is increased when the ductility of steel is reduced by: suppression of yield deformations, as may be caused by triaxial stressing; the use of relatively […]
EK335
Some brittle materials, such as cast-iron and concrete, contain large numbers of microscopic cracks in their structures. These are believed to give rise to high stress concentrations, thereby causing local […]
EK142
High local stress concentrations are not usually important in ductile materials under static loading situations, because the local yielding resulting form these concentrations causes a favorable redistribution of stress.
EK137
Theoretically, a member can only behave linearly while the maximum stress does not exceed the yield stress, and so the presence of residual stresses or stress concentrations will cause early […]
