This article describes a new procedure for automated generation of two-dimensional locally refined quadrilateral meshes gear drives. In this procedure, base mesh is generated using multiblock meshing procedure. Then, selected elements the are subdivided to obtain in certain parts teeth. The proposed completed with quality enhancement technique, which based on an optimization-based smoothing. It...

The effect and behaviour of soil - framed-structure interaction (SSI) under dynamic load conditions are presented in the paper. All civil engineering structures involve various types structural elements that direct contact with soil. Hence, a new thin-layer interface element, based on concept finite element method, is formulated. formulation elaborated using combination degrees freedom top bott...

The finite element error and adaptive analysis are implemented in procedures to increase the reliability of numerical analyses. In this paper, mesh-free error-recovery technique based on moving least squares (MLS) interpolation is applied recover errors stresses displacements incompressible elastic solutions estimated energy norms. effects types (triangular quadrilateral elements) formation pat...

We present and use a system of adaptive procedures for large-deformation finite element analysis of elastic and elastoplastic problems using the h-refinement approach. The procedures include a pointwise indicator for error in stresses, a pointwise indicator for error in plastic strain increments, a quadrilateral element mesh generator for generating completely new meshes on the deformed configu...

We describe and implement a symbolic algebra for scalar and vector-valued finite elements, enabling the computer generation of elements with tensor product structure on quadrilateral, hexahedral and triangular prismatic cells. The algebra is implemented as an extension to the domain-specific language UFL, the Unified Form Language. This allows users to construct many finite element spaces beyon...

This work aims at presenting a novel four-node quadrilateral element, which is enhanced by integrating with discrete shear gap (DSG), for analysis of Reissner-Mindlin plates. In contrast to previous studies that are mainly based on three-node triangular elements, here we, the first time, extend DSG elements. We further integrate fictitious point located center element into present formulation e...
