Expand description
Solid mechanics functionality for fenris.
Modules§
Structs§
- Gravity
Source - A source for the gravitational force.
- Material
Elliptic Operator - A wrapper that turns any hyper elastic material into an elliptic operator for use
with
fenrisassembly operations.
Traits§
- Hyperelastic
Material - A hyperelastic material defined by its energy density $\psi(\vec F)$.
- Physical
Dim - A fixed-size dimension corresponding to physical space.
Functions§
- compute_
batch_ contraction - Helper function to ease implementation of
HyperelasticMaterial::accumulate_stress_contractions_into. - deformation_
gradient - Compute the deformation gradient $\vec F$ given the displacement gradient $\nabla \vec u$.
- log_
det_ F - Compute $\log(\det \vec F)$ for the deformation gradient $\vec F$ given $\pd{\vec u}{\vec X}$.
- u_
grad_ from_ F - Compute the displacement gradient $\nabla \vec u$ given the deformation gradient $\vec F$.
