1. Warhead penetration in concrete protective structures
Sammanfattning : The analysis of penetration of warheads in concrete protective structures is an important part of the study of weapon effects on protective structures. This type of analysis requires that the design load in the form of a warhead is determined, and its characteristic and performance within a protective structure is known. LÄS MER
2. Behaviour of pretensioned bolts in friction connections : towards the use of higher strength steels in wind towers
Sammanfattning : During recent years wind energy has established as an alternative to commonenergy sources. To advance its competitiveness, the costs for the constructionof a wind tower have to be reduced. One possible option is the use of frictiongrip joints instead of flange connections to join various tower segments in atubular steel tower. LÄS MER
3. Concepts for hot sheet metal forming of titanium alloys
Sammanfattning : To increase the competitiveness of the Swedish aero engine industry alternative manufacturing methods for load carrying aero engine structures are desired, in order to reduce product cost and enable weight reduction and thereby fuel consumption. Traditionally, these structures mainly consist of large-scaled single castings of e.g. LÄS MER
4. Numerical analysis of concrete elements strengthened with carbon fiber reinforced polymers
Sammanfattning : Due to the growing number of ageing reinforced concrete structures such as buildings and bridges, there is an increasing interest in condition assessment and strengthening methods. Deterioration processes and demands for higher loads contribute to this interest. LÄS MER
5. High Performance Manufacturing of Advanced Thin Plates ─ Forming of Titanium and Stainless Steel Materials
Sammanfattning : The manufacturing industry represents a highly important sector of the Swedish economy. The increasing demands placed on the quality and performance of products that are manufactured places increasing demands on the manufacturing processes involved. LÄS MER
