1. Strong blast wave interaction with multiphase media
Abstract : The interaction of a blast wave propagating in air with different fluids like water column, aqueous foam and thermal/density inhomogeneity have been studied both experimentally and numerically. The blast waves were generated at atmospheric conditions in a newly constructed exploding wire facility. READ MORE

2. Impulse noise and brain injury. An experimental study in rats
Abstract : Abstract. Pressure waves, experienced as impulse noise, affect many body organs, although most attention has been paid to the inner ear. Impulse noise is produced by e.g. READ MORE

3. Models for analysis of shotcrete on rock exposed to blasting
Abstract : In underground construction and tunnelling, the strive for a more time-efficient construction process naturally focuses on the possibilities of reducing the times of waiting between stages of construction. The ability to project shotcrete (sprayed concrete) on a rock surface at an early stage after blasting is vital to the safety during construction and function of e. READ MORE

4. Structural Behaviour in Concrete Frame Corners of Civil Defence Shelters Non-linear Finite Element Analyses and Experiments
Abstract : From a safety point of view it is important that a concrete structure, apart from necessary load capacity, also is able to show ductile behaviour that allows redistribution of forces so that a local failure not lead to total collapse of the structure. A structure's ability to exhibit such behaviour is highly dependent on the reinforcement detailing of the joint connections between its independent members. READ MORE

5. On the Operational Efficiency in Open Pit Mines
Abstract : Open pit mines constitute more than half of global minerals production. Yet most of the large, high-grade, and close to the surface deposits have been depleted or are currently in production. Besides, volatility in commodity prices and stringent environmental regulations limit the up-scaling expansions in large open pits. READ MORE
