Elastic Energy
Elastic energy expressions for the Solid Rotor and Beam Rotor interfaces are similar to the Solid Mechanics and Beam interfaces in the Structural Mechanics Module. For details on the elastic energy, see the
Structural Mechanics Module User’s Guide
.
In the Beam Rotor interface, the strain energy density is split into membrane, bending, and shear parts, which are then summed into a total strain energy density.
The strain energy density for all elastic domains is integrated to give a total elastic strain energy, which contains all elastic energy stored in each physics interface.
