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.
