Welcome to the IFEM-Elasticity wiki!

The structure of IFEM is that you have a core library and several applications built on top of this library. IFEM-Elasticity (this repository) is one of those applications. To start using IFEM-Elasticity you will first need to clone and compile the core library, followed by cloning and building this module. The default location to clone applications is in the Apps-folder of your IFEM clone.

IFEM-Elasticy consists of two applications:

• LinEl - Linear elasticity problems

  • 2D and 3D elasticity problems
  • Beam and bar/cables in 2D space
  • Kirchhoff-Love plate and shell problems
  • Static analysis
  • Eigenvalue analysis (free vibration and linearized buckling)
  • Adaptive analysis based on a posteriori error estimates

• ShellEl - Nonlinear shell problems

  • Geometrically nonlinear Kirchhoff-Love shells
  • Quasi-static analysis with prescribed load increments
  • Path-following analysis with arc-length method
  • Adaptive mesh refinement in each load increment
