in fracture mechanics the symbol k stands for?
the stress intensity factor
next, irwin adopted the additional assumption that the size and shape of the energy dissipation zone remains approximately constant during brittle fracture. this assumption suggests that the energy needed to create a unit fracture surface is a constant that depends only on the material. this new material property was given the name "fracture toughness" and designated "g". today, it is the critical stress intensity factor "k", found in the plane strain condition, which is accepted as the defining property in linear elastic fracture mechanics.
