Computational Modelling of Concrete Structures Subjected to High Impulsive Loading

Steel versus Steel-reinforced Concrete Bridges: Environmental Assessment

Bridge material selection has traditionally been b~ed on e.ngineering and economi~ criteria. With the increasing interest of the public, industry, and government m sustainable:: development, en~lronmental. assessment in construction is becoming more important. However, we need metrtcs and data on deSign alternatives for effective decision making. In this paper, we present results of a life cycl...

Three-Dimensional Dynamic Analyses of Track-Embankment-Ground System Subjected to High Speed Train Loads

A three-dimensional finite element model was developed to investigate dynamic response of track-embankment-ground system subjected to moving loads caused by high speed trains. The track-embankment-ground systems such as the sleepers, the ballast, the embankment, and the ground are represented by 8-noded solid elements. The infinite elements are used to represent the infinite boundary condition ...

Deformation Criterion of Low Carbon Steel Subjected to High Speed Impacts

A study has been carried out to examine effects of blast loading on the microstructure deformation response of A572 Grade 50 low carbon structural steel. Symmetrical planar impact experiments have been carried out using a single stage gas gun to drive projectiles to velocities between 200 and 500 m/sec resulting in low to moderate shock loading of disc type steel specimens. Longitudinal stress ...

Modelling the structure changes in quenchable steel subjected to grinding

This paper analyzes the consequences of the microstructural changes in a quenchable steel component subjected to grinding. The model takes into account the coupling of the temperature history and stress field in the grinding, where the temperature field is assessed by Jager’s model and the stress field is analyzed by means of an embossed grid method. The effects of the dislocation density and g...
