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

Chúng tôi vui mừng thông báo rằng GS.TS. Le Khanh Chau và các đồng nghiệp gần đây đã xuất bản công trình của họ có tựa đề "Asymptotically accurate and locking-free finite element implementation of first order shear deformation theory for plates" trên tạp chí Computers & Structures.

Tóm tắt:

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.
