Coupling of BEM and FEM by a multiplicative Schwarz method and its parallel implementation

E. Stein, M. Kreienmeyer

The boundary element method (BEM) and the finite element method (FEM) may be computationally expensive if complex problems are to be solved; thus there is the need of implementing…

Continuation methods for tracing the equilibrium path in flexible mechanism analysis

Alberto Cardona, Alfredo Huespe

Presents an implementation of continuation methods in the context of a code for flexible multibody systems analysis. These systems are characterized by the simultaneous presence…

Steady state elastodynamics solutions using boundary spectral line strips

Ofer Michael, Jacob Avrashi, Giora Rosenhouse

The 2D frequency domain boundary integral equation is solved by the boundary spectral strip method. Using an expansion for frequency domain elastodynamics kernel we reduce its…

A general three‐dimensional contact procedure for implicit finite element codes

Issam Doghri, Arthur Muller, Robert L. Taylor

This paper presents a general procedure for solving 3D contact problems with implicit finite element codes. Emphasis is put on generality and robustness. Bodies in contact can be…

Application of MATHEMATICA to the optimal design of composite shells for improved buckling strength

M. Walker, T. Reiss, S. Adali, P.M. Weaver

The optimal design of a laminated cylindrical shell is obtained with the objectives defined as the maximisation of the axial and torsional buckling loads. The ply angle is taken…

Optimising engineering problems using genetic algorithms

M.F. Yeo, E.O. Agyei

This paper deals with the optimisation of engineering problems using genetic algorithms. The process is discussed and the various stages of the genetic algorithm described. In…
