Considering this, an additional element that only has shear stiffness is used. The increment of the shear strain, dγ, in the local coordinate system is related to the increments of the nodal displacements {du s}, which can be seen below (Bathe, 1982)

Strain represents the displacement between particles in the body relative to a reference length. Deformation of a body is expressed in the form x = F(X) where X is the reference position of material points of the body. Such a measure does not distinguish between rigid body motions (translations and rotations) and chang…
