- Detta är en avhandling från Stockholm : KTH Royal Institute of Technology
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.

2. Blast and Impact Loaded Concrete Structures - Numerical and Experimental Methodologies for Reinforced Plain and Fibre Concrete StructuresDetta är en avhandling från Gothenburg : Chalmers tekniska högskola
Sammanfattning : For decades the focus of civil protection has been on civil defence shelters to withstand the threat of warfare and protecting civilians. In latter years, the general focus has often shifted towards the protection of specific targets that host functions important to society. LÄS MER
- Detta är en avhandling från Institutionen för systemteknik
Sammanfattning : Continuum mechanics is used to model the mechanical behaviour of concrete structures subjected to high rates of loading in defence applications. Large deformation theory is used and an isotropic elastic-plastic constitutive equation with isotropic hardening, damage and strain rate dependent loading surface. LÄS MER
- Detta är en avhandling från Luleå : Luleå University of Technology
Sammanfattning : Comminution test methods used within mineral processing have mainly been developed for selecting the most appropriate comminution technology for a given ore, designing a grinding circuit as well as sizing the equipment needed. Existing test methods usually require comparatively large sample amounts and are time-consuming to conduct. LÄS MER
