RECENT GRANTS

Development of Advanced Methods for Theoretical Prediction of Shakedown Stress States and Physically Based Enhancement of Experimental Data, sponsored by US Department of Transportation, contract number DTFR 53-95-G-00055, 1995-2003

Development of computer packages for an adaptive solution of elastic--visco--plastic problems with internal variables , sponsored by the Polish Committee for Scientific Research (KBN), PB/0314/T11/97/12, 1997-1998

A mesh free finite difference method applicable to irregularly distributed nodes is being developed for both local and global formulations. The research is oriented on: mesh generation, MWLS approximation, higher order and quality finite difference operators, error analysis, adaptivity, multigrid approach, FDM/FEM combinations.
