Stress Analysis

Stress Analysis

Industry relevance

The stress margin is one of the fundamental margins for a structure, which also goes to determine the fatigue life / damage tolerance of the structure depending on the nature of the stresses. Generally components are loaded multiaxially , hence combining stresses to assess failures is a must. Prestress due self weight or joint or heat treatment also must be accounted for, apart from other obvious sources.

Example Optimum shaft sizing from stress perspective.

Learning outcomes
Treated with calculus, and trigonometry
  •   Ability to compute stresses in a multi axial loading situation and combine the stresses
  •   Ability to predict failure of the component: von Mises criterion (Stress margin only: the text book discusses stress lifing in detail).
  •   Ability analyze axisymmetric components subject to rotation, temperature and pressure loading including interference fits. (material modelling with temperature driven properties)
  •   Ability to derive material matrices (relation between stress and strain) for various loading situations ( plane stress, plane strain, axisymmetric loading situation)
  •   Detailed understanding of stress concentration, principle of superposition for multiaxial loading.
  •   Understanding of ductile and brittle overload fractures also detailed Ideas of crack initiation and propagation including critical stress intensity factor.
