Remarks

The parameter (3) is the warping function ω.

The parameters (4) and (5) are partial derivatives of the warping function ω, namely, ωy and ωz.

The attached material needs to be an OS material. Use a wrapper, for example, OS146 (for 3D host material) and OS146S (for 1D host material with linear elastic shear response).

Example
