Four-node Plate Elements with Assumed Shear Strain that Satisfy the Patch Test

We present the method of deriving mixed finite elements for Mindlin plates from a pure displacement approach, by reducing the general expression for the shear strain, while retaining its ability to pass the standard constant curvature path test. Two types of finite elements are constructed and presented on some standard benchmark problems with comparable elements from literature.
