Asymptotically accurate and locking-free finite element implementation of first order shear deformation theory for plates

We are happy to announce that Prof. Le Khanh Chau and colleagues recently published their work entitled "Asymptotically accurate and locking-free finite element implementation of first order shear deformation theory for plates" in the Computers & Structures.

Abstract:

A formulation of the asymptotically exact first-order shear deformation theory for linear-elastic homogeneous plates in the rescaled coordinates and rotation angles is considered. This allows the development of its asymptotically accurate and shear-locking-free finite element implementation. As applications, numerical simulations are performed for circular and rectangular plates, showing complete agreement between the analytical solution and the numerical solutions based on two-dimensional theory and three-dimensional elasticity theory.
