1. Adhesive joining for crashworthiness : material data and explicit FE-methods
Abstract : Today, crash simulations replace crash testing in the product development phase in theautomotive industry. High quality simulations enable shorter product development time andhigher competitiveness. READ MORE

2. The Hemming Process: A Numerical and Experimental Study
Abstract : Finite element simulations of hemming, a method used in the automotive industry to join two sheet metal panels by bending the flange of the outer panel over the inner one, are dealt with in this thesis. This method is used mainly for assembly of closures in automotive bodies (i.e. side doors, hoods, trunk lids and tailgates). READ MORE

3. On the Arbitrary Lagrangian-Eulerian Finite Element Method
Abstract : This thesis has been devoted to the study and development of algorithms for Finite Element (FE) simulations of mechanical processes involving large deformations. Aspects of three different formulations have been considered:(i) The single material Arbitrary Lagrangian-Eulerian (ALE) formulation is a method where the FE mesh is allowed to move independently to the material flow.

4. On Error-Controlled Numerical Model Reduction for Linear Transient FE² Analysis
Abstract : Multiscale modeling is of high interest in the engineering community due to its ability to capture the overall response, while still accounting for processes and structures on underlying fine scales. One standard approach to multiscale modeling is the so-called FE² procedure, where the classic constitutive relation is replaced by a boundary value problem on a Representative Volume Element (RVE) comprising the underlying microscale features.

5. Finite element modelling of hydroelasticity in hull-water impacts
Abstract : The work in this thesis focuses on the use of explicit finite element analysis (FEA) in the modelling of fluid-structure interaction of panel-water impacts. Paper A, considers modelling of a two-dimensional rigid wedge impacting a calm water surface. READ MORE
