Linear Elastic

The various stiffness terms (bending stiffnesses EIyy and EIzz, torsional stiffness GJ, and axial stiffness EA) are calculated from values you specify for Young’s modulus E and shear modulus G, and from the values of the cross-section properties I, A and J. EIyy and EIzz are necessarily equal in this case.
