16. Application of Differential Geometry to Elasticity and Corresponding Discrete Models
Sammanfattning : The amazing development in technology and industry during the last half of the twentieth century has opened totally new research fields. One of them is computational mechanics. Suddenly very complex, three-dimensional nonlinear engineering problems could be solved as a consequence of explosive advances in computers and numerical schemes. LÄS MER
17. Foam modeling including pore gas interaction for crashworthiness analysis
Sammanfattning : Foams are used in vehicles for three main functions: enhancing comfort, e.g.soft foams used in seats cushions, energy absorbtion, e.g. LÄS MER
18. Effects of deep excavations in soft clay on the immediate sourroundings-Analysis of the possibility to predict deformations and reactions against the retaining system
Sammanfattning : When excavating in an urban environment, the evaluation of the magnitude and distribution of ground movements is an important part of the design process, since excessive movements can damage adjacent buildings and utilities. In order to minimize movement of the surrounding soil, a retaining wall support system is used for deep excavations to provide lateral support. LÄS MER
19. Holistic Assessment of Survival Time after Ship Collision
Sammanfattning : Collisions between ships contribute to ship losses even in modern time, and the International Maritime Organization (IMO) strives towards a more risk-based view on addressing the damage stability of ships. This thesis presents a holistic methodology for computing the consequences of ship collisions. LÄS MER
20. Computational Road Mechanics - with Emphasis on FE-analysis of Rutting
Sammanfattning : A road is a very complex structure in which a large number of different structural phenomena occur simultaneously that effects its expected lifetime. The structure itself is of a multi-layer type, in which the different layers consist of materials that exhibit vastly different physical behaviors when subjected to various kinds of loads. LÄS MER
