Select the true statement regarding the fracture of materials
A. Polymer fracture is highly dependent on the testing conditions, such as temperature and strain rate, but is not affected by the nature of bonding of the molecular chains
B. For metals, fracture only occurs along the boundaries created by the differently oriented grains because the high energy interfaces created by mismatched lattices
C. A blunt crack tip will result in a faster fracture than a narrow tip because of the larger crack tip radius
D. Brittle fracture involves rapid crack propagation with a high degree of plastic deformation in the direction perpendicular to the tensile stress
E. The fracture strength is more heavily influenced by the degree, shape, and orientation of microscopic defects than the nature of atomic bonding of the constituent atoms
