Abstract

A dynamic analysis of the stabilized conforming nodal integration meshfree Mindlin-Reissner plate formulation is carried out and compared with the meshfree approach using Gauss integration. The dispersion performance is discussed with particular reference to the locking-free characteristic of the semidiscrete formulation. Subsequently, the space-time fully discretized meshfree equations are established by further invoking the Newmark time integration method which is followed by a transient analysis. The numerical results of both dispersion and transient analyses demonstrate that the meshfree formulation based on the conventional Gauss integration shows severe locking problems while the stabilized conforming nodal integration meshfree plate formulation is locking-free and has very high accuracy.
