Linear problems
###############

Elastostatics :
standard continuous galerkin
* 2D plane stress/strain
* 3D isotropic, orthotropic
* axisymmetric

discontinous galerkin
-> volumetric locking

mixed formulation using Hu-Washizu
-> volumetric locking

Elastodynamics 
* time integration Newmark scheme, theta

Poroelasticity

Mixing continuum and interfaces
* elastic interfaces/supports (beam on elastic foundation)

Linear Fracture Mechanics
* G-theta method to compute J-integral and stress intensity factors

Homogenization in elasticity
-> treatment of rigid particles with Lagrange multipliers

Linear Buckling
