Numerical Techniques for the Coupling Stiffness Matrix of FEM and BEM

1992
Combining the boundary integral equation method (BEM) with the variational formulation (FEM) yields, as a final result, either a symmetric formulation or a positive definite one. In order to develop a coupling procedure which has both of these properties, we consider Courant’s idea in elasticity. We convert the strain energy term into a boundary energy.

Simple derivation of the stiffness matrix for axial/torsional coupling of spiral strands

Computers & Structures, 1995
Abstract Coupled extensional-torsional behaviour of realistic multi-layered helical strands is addressed. Simplified routines are presented for obtaining the upper and lower bounds to various strand stiffnesses. Such straightforward formulations (aimed at practising engineers) have been derived by extensive theoretical parametric studies on a number ...

Coupled bending–torsional dynamic stiffness matrix for beam elements

International Journal for Numerical Methods in Engineering, 1989
AbstractExplicit expressions for the coupled bending–torsional dynamic stiffness matrix of a uniform beam element are derived in an exact sense by solving the governing differential equation of the beam. Implementation of the derived dynamic stiffness matrix in a space frame computer program is discussed with particular reference to an established ...
