Abstract
In this paper, a finite‐element based 3‐D FDTD space/time subgridding scheme is presented. A classical Yee scheme is obtained strictly inside domains having different space and time discretizations. Considering one domain, the presence of the other domain is taken into account through an electric‐field excitation distributed throughout the mesh interface. The validity of the proposed technique is demonstrated through its application on two test cases: a Hertzian dipole and a mobile‐phone antenna. © 2002 John Wiley & Sons, Inc.

## Abstract We present a finite element formulation based on a weak form of the boundary value problem for fully coupled thermoelasticity. The thermoelastic damping is calculated from the irreversible flow of entropy due to the thermal fluxes that have originated from the volumetric strain variatio
For the stress analysis of planar deformable bodies, we usually refer to either plane stress or plane strain hypothesis. Three-dimensional analysis is required when neither hypothesis is applicable, e.g. bodies with finite thickness. In this paper, we derive an 'exact' solution for the plane stress
We use the updated Lagrangian and the co-rotational finite element methods to obtain solutions for geometrically non-linear flexible sliding beams. Finite element formulations are normally carried out for fixed domains. Since the sliding beam is a system of changing mass, first we discretize the sys
