3.1 Crack is an imperfection caused by a local rupture in the solid state, which may arise from the effect of cooling or stresses. Cracks are very significant than other type of imperfections, as crack will produce large stress concentration at the crack tip, making them more likely to cause fracture.Type of cracks:Longitudinal crackstransverse crackscrater...
