1. Shear in Concrete Structural Elements Subjected to Dynamic Loads
Abstract : Concrete structural elements subjected to severe dynamic loads such as explosions at close range may cause shear failures. In the Oklahoma City bombing in 1995 two concrete columns on the ground level were reported to have failed in shear. READ MORE

2. Behaviour of fracture process zones in concrete influenced by simultaneously applied normal and shear displacements
Abstract : The thesis deals with the determination of the post peak behaviour of concrete in pure tension, and combined tension (compression) and shear. A test arrangement has been developed in order to determine the post peak behaviour of concrete expressed as stress - displacement curves. READ MORE

3. FRP shear strengthening of reinforced concrete beams
Abstract : The shear failure mechanisms of flexural reinforced concrete (RC) members is highly complex; its precise details cannot be explained with simple analytical relationships, and are the topic of considerable scientific debate. The studies described and examined the three most used shear theories in the world – the fixed angle truss model (45°TM), the variable angle truss model (VAT), and modified compression field theory (MCFT).

4. Drift ballooning and ITG instabilities in tokamak plasmas
Abstract : A major aim in fusion research is to understand, predict and control confined plasma instability in terms of equilibrium, stability and transport. Substantial progress has been made in recent years in understanding stability and transport in terms of MHD instability and drift wave instabilities. READ MORE
