Inverse Problems in Structural Mechanics
… with the solution of three inverse problems in structural mechanics. The first one is load updating for finite element models (FEMs). A least squares fitting is used to identify the load parameters. The basic studies are made for geometrically linear and nonlinear FEMs of beams or frames by …

Towards Scalable Parallel Simulation of the Structural Mechanics of Piezoelectric-Controlled Beams
In this thesis we present a parallel implementation of an engineering code which simulates the deformations caused when forces are applied to a piezoelectric-controlled smart structure. The parallel simulation, whose domain decomposition relies on the finite element representation of the structure, …
