Constitutive law for loading (thin) 3D shell elements.
This law is used for mechanical analysis of shells, loaded by uniform pressure and shear, normal and tangential to the mid-line $\xi$ at any moment, or in the global axes.
Loading can be driven either by force multiplicator (MULTF) or displacement multiplicator (MULTD).
