Recent Activities

development of the multipoint approximation concepts for the structural optimization problems with computationally expensive and noisy objective and constraint functions, evaluated by FEM;
application of the genetic programming methodology to the choice of the structure of approximations;
application of genetic algorithms to discrete optimization problems, e.g. optimium design of structural steelwork;
application of advanced optimization techniques to various structural and multidisciplinary design problems including optimization of:

thermodynamic characteristics of Stirling engines (Ansaldo Vølund, Denmark, collaboration with Dr H. Carlsen of The Technical University of Denmark);
dynamic characteristics of a tractor-trailer combination (DAF Trucks NV, The Netherlands, collaboration with Professor P. Meijers and Dr V. L. Markine of Delft University of Technology);
aerofoils (BAe Sowerby Research Centre).

application of multipoint approximations in conjunction with adaptive mesh refinement techniques to shape optimization of thin-walled structures;
parameter identification of constitutive models describing the nonlinear mechanical behaviour of engineering materials;
structural damage recognition formulated as a systems identification problem;
finite element analysis and design sensitivity analysis of various structural systems.
