Compute Finite Beam Strain

Compute a rotation increment for finite rotations of the beam and computes the small/large strain increments in the current rotated configuration of the beam.

Description

This class computes the rotation matrix that relates the global coordinate system to the current beam local coordinate system for large rotation scenarios in beam elements. Using this rotation matrix, the small/large strain increments in the current local configuration of the beam are also computed by this class. Please refer to C0 Timoshenko Beam for details.
