Beam Elements in Optistruct/HyperMesh
A beam element is a one-dimensional finite element with two nodes, one at each end. Each node possesses six degrees of freedom: three translational (TX, TY, TZ) and three rotational (RX, RY, RZ), corresponding to translation along and rotation about the X, Y, and Z axes. Beam elements are capable of resisting axial forces,…
