1. 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

2. Response of cable-stayed and suspension bridges to moving vehicles : Analysis methods and practical modeling techniques
Abstract : This thesis presents a state-of-the-art-review and twodifferent approaches for solving the moving load problem ofcable-stayed and suspension bridges. The first approach uses a simplified analysis method tostudy the dynamic response of simple cable-stayed bridgemodels. READ MORE

3. Search for efficient time integration methods in structural dynamics for finite element meshes with large variations of properties
Abstract : Direct time integration methods are the most commonly used solution algorithms for analysis of non-linear transient phenomena in finite element computations. One major disadvantage with these methods is that stability and accuracy of the computation are governed by the smallest element in the mesh assuming all other properties constant. READ MORE

4. Computational Solid Wave Propagation Numerical Techniques and Industrial Applications
Abstract : For wave propagation and many other physical phenomena, the dynamic effects are vital. In industrial applications, such problems are very complex and generally have to be treated by means of numerical methods. READ MORE

5. Energy-momentum conserving time-stepping algorithms for nonlinear dynamics of planar and spatial Euler-Bernoulli/Timoshenko beams
Abstract : Large deformations of flexible beams can be described using either the co-rotational approach or the total Lagrangian formalism. The co-rotational method is an attractive approach to derive highly nonlinear beam elements because it combines accuracy with numerical efficiency. READ MORE
