A. Ductile fracture of a stressed material, which exhibits a large plastic deformation is commonly
caused by the formation and coalescence of voids in the necked region
B. Brittle fracture is caused by the propagation of pre-existing cracks in the material and involves minimum plastic deformation
C. Fatigue fracture of a material is always brittle in nature and takes place due to the existence of
line imperfections
D. Brittle materials are generally tested in tension
