TENSILE STRESS, TENSILE STRENGTH
Tensile fracture - separation of a body across a surface normal to the
direction of least principal stress, where s 3<0. There is no offset
parallel to the fracture surface. The relationship between the tension
fractures and the principal stresses follows from the observation of zero
offset on the fractures. Zero offset indicates zero shear stress is
applied to this surface, therefore it must be a principal plane
