-Implementing strain calculator for shell implements that computes the strain tensor in the shell local coordinate system. Modified the strain calculator so that the strains are calculated in the element local coordinate system. This will enable use of the shell element with the existing material models in the long run, through the use of the weak plane stress kernel. Added the stress calculators and linear elastic isotropic elasticity tensor class for shell elements that has weak plane stress assumption built in it. Also, added stress divergence kernel for shell elements using the stresses and test function gradients calculated in the shell local coordinate system. Began testing it on bending of a 4 element cantilever beam bending problem from Dvorkin and Bathe paper. The residual is diverging, mostly likely due to a bug in the linear elastic isotropic elasticity tensor for the shell.
+A 4-noded shell element is being implemented in MOOSE based on the [citet:dvorkin1984continuum] formulation. This shell element can be used for problems that involve small or finite rotations. An initial tested version of this element would be available in MASTODON by end of Summer, 2019.
