Speech Title: Eigenvalue analysis of structural vibration problem with uncertainty using an exact solution method and its parallel algorithm
Abstract: Significant uncertainties caused by system complexities, model inaccuracies, physical imperfections and others, exist practically in all the engineering structures to varying degrees. In this speech, we will attempt to address the structural vibration problems with uncertainty. Considering limited available information, we employ interval parameters to quantify the uncertainties in structural system. Also an exact solution method for evaluating the structural eigenvalue bounds and its novel proof using convex set theory will be discussed. Furthermore, we will demonstrate a parallel algorithm exploited to improve computational efficiency of the exact solution method. Compared with the existing methods, the contribution of this work is not only to obtain the exact eigenvalue bounds, but also be easy to couple with existing deterministic finite element codes for solving many large-scale engineering structures with uncertainties. Finally, Numerical examples will be performed for the purpose of validation and demonstration.
