The maximum principal stress criterion
SpletThe maximum distortion criterion (also von Mises yield criterion [1]) states that yielding of a ductile material begins when the second invariant of deviatoric stress reaches a critical value. [2] It is a part of plasticity theory that mostly … The maximum stress criterion assumes that a material fails when the maximum principal stress in a material element exceeds the uniaxial tensile strength of the material. Alternatively, the material will fail if the minimum principal stress is less than the uniaxial compressive strength of the material. Prikaži več Material failure theory is an interdisciplinary field of materials science and solid mechanics which attempts to predict the conditions under which solid materials fail under the action of external loads. … Prikaži več Material failure can be distinguished in two broader categories depending on the scale in which the material is examined: Microscopic failure Microscopic material failure is defined in terms of crack initiation and propagation. Such … Prikaži več • Fracture mechanics • Fracture • Stress intensity factor Prikaži več In materials science, material failure is the loss of load carrying capacity of a material unit. This definition introduces to the fact that material failure can be examined in different scales, from microscopic, to macroscopic. In structural problems, where the … Prikaži več Failure of brittle materials can be determined using several approaches: • Phenomenological failure criteria • Linear elastic Prikaži več A yield criterion often expressed as yield surface, or yield locus, is a hypothesis concerning the limit of elasticity under any combination of stresses. There are two interpretations of … Prikaži več

SpletGraphically, the maximum shear stress criterion requires that the two principal stresses be within the green zone indicated below, Von Mises Criterion. The von Mises Criterion (1913), also known as the maximum distortion energy criterion, octahedral shear stress theory, or Maxwell-Huber-Hencky-von Mises theory, is often used to estimate the ...

Splet26. apr. 2024 · The general state of stress can be represented by a symmetric 3 x 3 matrix. The three principal stresses are conventionally labelled σ1, σ2 and σ3. σ1 is the maximum (most tensile) principal stress, σ3 is the minimum (most compressive) principal stress, and σ2 is the intermediate principal stress. Splet5.2. PLASTIC YIELDING UNDER MULTI-AXIAL STRESS STATES 119 5.2.1 Maximum Principal Stress (Lame) As the name indicates, the material breaks when the maximum principal stress I reaches the critical value c. This is simply stated in mathematical form, as: I c It turns out, this criterion is applicable to brittle materials. Concept Question 5.2.2.
