2. Nonlinear dynamics of flexible structures using corotational beam elements
Abstract : The purpose of this thesis is to develop corotational beam elements for the nonlinear dynamic analyse of flexible beam structures. Whereas corotational beam elements in statics are well documented, the derivation of a corotational dynamic formulation is still an issue. READ MORE

3. Corotational formulation for nonlinear analysis of flexible beam structures
Abstract : Flexible beam structures are popular in civil and mechanical engineering. Many of these structures undergo large displacements and finite rotations, but with small deformations. Their dynamic behaviors are usually investigated using finite beam elements. A well known method to derive such beam elements is the corotational approach. READ MORE

5. Modeling of losses in power transformers from dc to the low kilohertz range
Abstract : The development of HVDC converters, local generation and tractions systems increases the demand for power converters. While a lot of studies have been conducted on the power electronics, there are still open questions concerning the contained power transformer that operates at a few kilohertz. READ MORE
