WebAccording to the failure criterion (16.8), failure occurs when the local maximum tensile stress exceeds the critical tensile stress σ c and makes the flaw unstable. This … WebIt’s the maximum tensile stress the material can handle before permanent deformation. Ultimate strength refers to the maximum stress before failure occurs. Fracture strength is the value corresponding to the stress at which total failure occurs. Stiffness is how a component resists elastic deformation when a load is applied.
