16. Structural behaviour of lightweight deck structures and dynamics of vehicle-deck interactions
Sammanfattning : .... LÄS MER
17. Damage Tolerance of Impacted Composite Sandwich Structures
Sammanfattning : This thesis deals with damage tolerance of impacted sandwich structures for load bearing applications. Composite sandwich structures find wide application as lightweight solutions in aerospace components, since weight reduction and less fuel emissions are primary concerns for aircraft manufactures.

18. Subjective assessment of vibrations in lightweight floors
Sammanfattning : Lightweight steel floors arise a lot of attentions because of its advantages, such as cost effective, recyclable, and having a short construction period. On the other hand, low frequency vibrations induced by normal human activities get more and more complains for these types of structures. LÄS MER
19. Framework for holistic design of ferries focusing on lightweight ice going hulls
Sammanfattning : Waterborne public transportation (WPT) is slowly increasing in importance as an active component of public transportation networks in cities. City planners are looking at WPT to overcome urban congestion and pollution. LÄS MER
20. Active Junction Control and Piezoelectric Hybrid Damping for Improving the Acoustic Performance of Lightweight Structures
Sammanfattning : Weight reduction is a key factor in lowering the fuel consumption and thereby the greenhouse emissions from vehicles. However, reducing the weight normally results in a deterioration of the acoustic performance. Thus, the purpose of this thesis is to investigate damping treatments for lightweight vehicle panels.
