An Energy-based Overset Finite Element Method for Pseudo-static Structural Analysis

Abstract This paper addresses a simple energy-based overset finite element method (EbO-FEM) to solve pseudo-static deformation problems consisting of overlapped meshes based on the domain composition (DCM). scheme is non-iterative equation-based for enforcing continuity displacement field. Hence, consumes possible minimal computational costs with non-conforming overlapping meshes. The system’s total energy augmented constraint (CCE) which function gaps in field between two regions. Subsequently, conventional integration schemes, Gauss-point projection, and point-to-point are utilized discretize CCE. It confirmed that both schemes can yield accurate unique solutions region Further, we proposed dimensionless relative penalty parameter (DRP). We found DRP ranging 1 10 appropriate robustly obtain wide range scales, stiffness, geometries, supported by three numerical simulations without increasing after assembling global matrices vectors.
