Element Library NONLINEAR 3-D TRUSS ELEMENT The nonlinear 3-D truss element supports three translational degrees of freedom at each end of the member and a constant cross-sectional area. This element can only transmit axial forces. Topology 2 nodes Loading Forces Gravitational forces Acceleration forces Centrifugal forces Prescribed displacements Initial velocities Initial rotations Initial axial force Initial axial strain Dashpot damping Formulations Optional material damping Material nonlinear only Total Lagrangian Updated Lagrangian
