Finite element algorithm

The present paper considers the composite plate resting on an elastic pinned subjected to harmonic loads. The plate element model with high-order shear deformation theory and finite element algorithm is proposed in order to buckling analysis of the plate. As a result, the buckling domain is determined. Moreover, the effect of geometric parameters, elastic pins, and materials on the buckling of the plate is comprehensively investigated.

The article "Static behavior of FGP half-annular nanoplates resting on elastic foundation using nonlocal elasticity theory" presents an algorithm finite element for static bending analysis of the functionally graded porous (FGP) half-annular nanoplate resting on the elastic foundation (EF) using nonlocal elasticity theory. The FGP materials with two-parameter are the volume fraction index (k) and the porosity volume fraction (5) in two cases of even and uneven porosity. The EF includes Winkler-stiffness (k₁) and Pasternak- stiffness (k₂).

In paper "p-adaptive meshing for triangular nodal finite elements meshes", we present p-adaptive meshing algorithms (p-refinement and unrefinement) for triangular finite element meshes. The algorithms are designed to keep the computation cost low, and the neighboring elements are not too different in degree. In addition, we can prove that if we start with an admissible mesh, then each element can be refined at most once using the proposed algorithms. This is important because after a p-refinement there is no way to estimate its error without resolving the whole problem.

This paper proposes an optimal design “modern” approach for servomotors. This approach consists of the optimization algorithms at the initial analytical calculations and the modelling of the virtual prototype in order to reduce the costly and time-consuming prototyping loops of the “conventional” design method. The optimal design of a servomotor for robot application is verified by using finite element analysis (FEA) in terms of torque at low to high speeds.

This paper extends a numerical procedure for limit ananlysis of 3-D structures using node-based smoothed finite element method (NS-FEM) in combination with second-order cone programming (SOCP). The obtained discretization formulation is then cast in a form which involves second-order cone constraints, ensuring that the underlying optimization problem can be solved by highly efficient primaldual interior point algorithm. Furthermore, in the NS-FEM, the system stiffness matrix is computed using the smoothed strains over the smoothing domains associated with nodes.
