1. Fracture mechanics studies of non-yielding materials like concrete : modelling of tensile fracture and applied strength analyses
Sammanfattning : Fracture mechanics studies of non-yielding materials are presented. The studies are based on theoretical models for the macroscopical mechanical behaviour of materials during tensile stress induced fracture. A number of applied numercal analysis are indicated. LÄS MER
2. Quality-Driven Production of Aggregates in Crushing Plants
Sammanfattning : Aggregate quality is of great importance, and in this context it is essential to understand how various process parameters influence the product quality characteristics. Thus, there is a need for aggregate producers to improve their process knowledge. LÄS MER
3. Mehanics of Rock Fragmentation Static and Dynamic Laboratory Testing Applied to Aggregate Production
Sammanfattning : Knowing the strength properties of rocks is essential for calculating the stability of natural slopes, constructions in and on rock, excavations, blasting geometry, crushing, and drilling. When rock and rock masses are subjected to either dynamic or static loads, the tensile strength is determined by tests appropriate to the load type. LÄS MER
4. Assessment of bio-based fuel ash effects on magnesia refractory materials in quicklime production kilns
Sammanfattning : Limestone is calcined into quicklime in lime kilns at temperatures above 1000°C. Heat is supplied through combustion inside the kilns, which are insulated with a lining of refractory bricks to mitigate heat loss and to protect the kiln from the hot, chemically aggressive, and mechanically abrasive environment.

5. Physically based fibre kinking model for crash of composites
Sammanfattning : Passenger cars are a major emitter of global warming gases which has led to tighter regulations being imposed on car manufacturers. An efficient way to reduce emissions is to reduce the weight of the cars. LÄS MER
