1. Nonlinear dynamics of flexible structures using corotational beam elements
Sammanfattning : 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. LÄS MER
2. Corotational formulation for nonlinear analysis of flexible beam structures
Sammanfattning : 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. LÄS MER
3. Soil Degradation of Raised-beds on Orchards in the Mekong Delta Field and Laboratory Methods
Sammanfattning : Soil degradation is a complex process which may occur anywhere and at any time. It directly affects the physical, chemical and biological processes within the soil profile. Soil degradation can either be as a result of natural hazards or due to manmade actions, such as mismanagement on cropping patterns, soil preparation and cultivation practices. LÄS MER
