Content

  • Program structure: menu navigation, unit systems, modeling of the problem
  • Stress and strain measures

  • Stress concentrations at notches, holes

  • Geometry description: plane, spatial, rotationally symmetric problems

  • Applications of different materials: linear elastic, hyperelastic, inelastic, anisotropic material behavior

  • Modeling of support and boundary conditions

  • Discretization of components

  • Parameter identification and optimization: inelastic material parameters, geometry optimization

  • Comparison of numerical results with experimental deformation analyses (DIC)

 

Qualification goals
The students can deal with problems of higher strength theory with the help of a common, commercial finite element program (Abaqus). Based on a practical structural-mechanical problem (e.g. stress concentration), they can identify the necessary input variables of a finite element analysis (geometry description, material, bearing/boundary conditions, load and discretization) and feed them into the calculation program. Furthermore, students are able to critically interpret the results of the FE analysis.
