Theories of failure of stress
Webb26 nov. 2024 · Maximum Stress Criterion This assumes no interaction between the modes of failure, i.e. the critical stress for one mode is unaffected by the stresses tending to cause the other modes. Failure then occurs when one of these critical values, σ1u , σ2u and τ12u , is reached. WebbThe principal stresses will be taken to be ordered as The failure theory treated here is given by two coordinated but independent criteria: POLYNOMIAL INVARIANTS FAILURE CRITERION and COORDINATED FRACTURE CRITERION The coordination refers to the physical basis for the inception of the fracture criterion at T/C=1/2.

Constructions in soil can also fail due to shear; e.g., the weight of an earth-filled dam or dike may cause the subsoil to collapse, like a small landslide. Impact shear. The maximum shear stress created in a solid round bar subject to impact is given by the equation:
