Experimental and Finite Element Studies on Free Vibration of Areca Leaf Sheath Reinforced Polymer Composites [PDF]
Mechanics of Advanced Composite Structures, 2021 The present work deals with the experimental and finite element free vibration studies on areca leaf sheath reinforced polymer composites. In this study fundamental frequencies are obtained for five boundary conditions numerically (such as CFFF, CFCF ...

A Boundary Element Procedure for 3D Electromagnetic Transmission Problems with Large Conductivity
Mathematics, 2022 We consider the scattering of time-periodic electromagnetic fields by metallic obstacles, or the eddy current problem. In this interface problem, different sets of Maxwell equations must be solved both in the obstacle and outside it, while the tangential

p‐adaptive boundary elements [PDF]
International Journal for Numerical Methods in Engineering, 1986 AbstractThis paper presents the implementation of an adaptive philosophy to plane potential problems, using the direct boundary element method. After some considerations about the state of the art and a discussion of the standard approach features, the possibility of separately treating the modelling of variables and their interpolation through ...

Boundary Element and Finite Element Coupling for Aeroacoustics Simulations [PDF]
, 2014 We consider the scattering of acoustic perturbations in a presence of a flow. We suppose that the space can be split into a zone where the flow is uniform and a zone where the flow is potential.

Consistent dirichlet boundary conditions for numerical solution of moving boundary problems [PDF]
, 2008 We consider the imposition of Dirichlet boundary conditions in the finite element mod-elling of moving boundary problems in one and two dimensions for which the total mass is prescribed.

Crouzeix–Raviart boundary elements
Numerische Mathematik, 2009 The authors analyze a non-conforming boundary element method with discontinuous elements. More precisely, the use of piecewise linear Crouzeix-Raviart elements where jumps of basis functions across element boundaries have integral mean zero is studied. The meshes are triangular and regular, but the basis functions are not continuous.
