1. Analysis of underground concrete pipelines subjected to seismic high-frequency loads
Abstract : Buried pipelines are tubular structures that are used for transportation of important liquid materials and gas in order to provide safety for human life. During an earthquake, imposed loads from soil deformations on concrete pipelines may cause severe damages, possibly causing disturbance in vital systems, such as cooling of nuclear power facilities.

2. Numerical modelling considerations for analysis of concrete hydraulic structures subjected to high-frequency seismic loads
Abstract : Concrete hydraulic structures are of great importance in today's society. When situated in areas with hard bedrock, these structures may become extra vulnerable to seismic excitations as these here are dominated by high-frequency vibrations which can have disastrous consequences for slender structures.

3. Impact wave process modeling and optimization in high energy rate explosive welding
Abstract : Impact waves are used in many different industries and are classified according to whether they cause plastic or elastic deformations. In the plastic deformation mode, these waves can be used to produce special electrical joints. In the elastic deformation mode, they can be used to detect leakage or to measure the thickness of pipes. READ MORE

4. Evaluation of Innovative Rehabilitation Technologies Utilising Polymer Composites for Aging Sewer Systems
Abstract : Water and wastewater sewer system maintenance is among the costliest aspects of infrastructure investment. The replacement of deteriorated lines is a difficult and expensive process that causes community disturbance and is generally not conducted fast enough to meet demand. READ MORE
