1. On immediate/early loading of implant-supported prostheses in the maxilla
Sammanfattning : ABSTRACT Background: The original treatment protocol for osseointegrated implants prescribed an unloaded healing period of 3 to 6 months before connection of the prosthetic superstructure. During the last years shortened healing time and rapid loading have become more frequently used. LÄS MER
2. Concrete Structures Subjected to Blast Loading
Sammanfattning : The interest for building safety with regards to highly dynamic events such as close by explosion has accelerated after the recent decades of terrorist attacks. The interest has expanded from civil defence shelters and pure military targets to also include civil buildings used for different civil functions. LÄS MER
3. Strain rate dependent material model for polymer composites
Sammanfattning : We propose a micromechanical model that is able to predict the nonlinear behaviour and failure of unidirectional fibre reinforced polymer composites subjected to dynamic loading conditions. This novel material model is heterogeneous on the micro level and homogeneous on the ply level. LÄS MER
4. Failure of thin-walled structures under impact loading
Sammanfattning : Increase in computational power during recent years contributed to a significant development in numerical methods in mechanics. There are many methods developed that address various complex problems, yet modelling of initiation and propagation of failure in thin-walled structures requires further development. LÄS MER
5. Concrete Structures Subjected to Fragment Impacts
Sammanfattning : As concrete is commonly used for protective structures, how a blast wave and fragment impacts from an explosion affect the concrete is an important issue. Concrete subjected to explosive loading responds very differently from statically loaded structures. LÄS MER
