Nichtlineare Finite-Elemente-Methoden (MB-51)

Nonlinear Finite Element Methods (Module MB-51, previously Module 9)

Contents

This course discusses the finite element method, discretisation techniques and solution strategies for problems in solid mechanics at large deformations.

  • Repetitorium of kinematics, stresses, balance relations and thermo-hyperelasticity
  • Strong and weak forms of balance of linear momentum and the heat equation in spatial and material description
  • Spatial discretization of the weak forms in spatial and material description - linearisation and stiffness matrices
  • Nonlinear truss elements
  • Nonlinear solution strategies
    • Newton's method
    • line search methods
    • arc length methods
  • Deformation dependent loads
  • Quasi-incompressibility
  • Nonlinear viscoelasticity

Prerequisites

Successful completion of the introduction course on Finite Element Methods I and II or equivalent experience. Experience in nonlinear continuum mechanics and scientific programming in Python (or Matlab, C, C++, Fortran) necessary.
