I have a model of a cantilever (fixed on one end, and free on all other boundaries) that bends in response to an internal stress field.
How can I calculate the amount of force this cantilever can exert on an external object?
The experimental analogue, as far as I know, is the blocking force--if you start with the cantilever in a flat state and physically obstruct the bending of the cantilever, how much force must you exert in order to keep the cantilever flattened out?
The model I'm using is a PDE that describes a non-linear, hyperelastic solid. For a given state of deformation, I can calculate the stress tensor and potential energy density throughout the cantilever.
So far, I have been using the finite element method to find the state of deformation in static equilibrium.
