When the Mindlin model is applied to analyze the thin plate under bending moment, the displacement of plate is much lower than the exact value. This phenomenon is caused by shear locking of model. Here, a new nonconforming quadrilateral element P1, which is one kind of discontinuous element and owns the Poisson locking-free property, was applied to Mindlin plate. The results prove that reduced P1- nonconforming element can solve shear locking problem. Topology optimal design of plate under bending moment was based on P1 nonconforming element, whose purpose was to obtain the minimum compliance for a given mass of plate. Topology optimal shape of the plate is verified by some typical bending plate model. This paper presents a new method to solve shear locking problem of Mindlin plate and it can be used to solve other domains.
