Detailed Description

template<typename TDomain>
class ug::SmallStrainMechanics::SmallStrainMechanicsElemDisc< TDomain >

This class assembles the equation of the static linear elasticity problem:

(1) - div(sigma) = f (2) sigma = C : epsilon (3) epsilon = 1/2 (nabla_u + nabla_u^T)

boundary conditions.

As common in the linear theory we identify the deformed configuration with the undeformed configuration. Therefore we do not have to distinguish between different stress measures. Here we use a pure displacement-ansatz to solve the coupled system above, i.e. the kinematic equation for the linearized strain tensor epsilon (3) is inserted in the material law (2) and the resulting stress tensor sigma is introduced in the momentum balance equation (1). Therein, the computation of the strain and the stress tensor is performed at the integration points! Following this approach, the only remaining unknown function is the displacement field u!

\TODO: in case of linear elasticity one can implement the voigt notation (exploiting symmetry of sigma and epsilon)

In order to compute the eigenfrequencies of a system by means of the eigenvalue problem the second time derivatives of u

rho * \frac{\partial^2 u}{\partial^2 t}

are considered in the momentum equation (1) and deliver a contribution to the mass matrix.
