1. Eigenfrequency Analysis FE-Adaptivity and a Nonlinear Eigenproblem Algorithm
Abstract : Engineering often pose the problem of computing the frequencies with which a system oscillates and the corresponding displacement patterns the system forms, and in case damping is present then the rates of which the amplitudes of the displacement patterns decay are also required. It is necessary to compute these quantities within a prescribed accuracy and the effort required for the computations should be minimised. READ MORE

2. Adaptive Finite Element Procedures in Structural Dynamics
Abstract : This thesis deals with a posteriori error estimation and adaptivity in finite element procedures for the analysis of structural dynamic problems. First, error estimation and adaptivity for the Newmark time integration method are studied. READ MORE
