Finite element model of Cairo metro tunnel-Line 3 performance

WP 5 - Computational Mechanics Geo - Metro Finite Element model ( GM _ R 3 ) : Improvements of Steering System and Suspensions MAIN REPORT

The Robust Project aims to improve scientific and technical knowledge on the main issues still open in the new European standards on road restraint system EN 1317 [1-2]. The knowledge acquired will form the basis of updated standards for EN1317 and lead to more advanced road restraint systems and improve road-users safety. This report is part of the deliverables from Work Package 5 (WP5)-Comput...

Performance evaluation of modified bentlegPlow using finite element approach

ABSTRACT-This paper aims to develop a new design of a bentleg (BL) plow and to determine its performance as compared to the conventional one using finite element approach. The difference between the modified and conventional BL plows is the direction of angle between the projection of cutting blade on horizontal plane normal to plow shank and the line perpendicular to the plow shank in the same...

Simulation of Metro Train Fire in an Underground Station of Tehran Metro Line 7

In this research a fire scenario was simulated in one of the stations of the line 7 of Tehran's subway system. The Line 7 is under construction and the ventilation system is under design. Fire was set for a stopping metro train at the platform of the station. A 160 meter length eight-car metro train with the forth wagon on the fire was studied. The heat release rate is based on a quadratic f...

An Algorithm for Finite Element Analysis of Tunnel Supports Based on the Winkler’s Theory

Finite Element Modelling of 3-3 Piezocomposites

Efforts to improve the properties and reliability of piezoelectric materials have often concentrated on processing dense ceramic material by techniques such as fine particle size powder production, grain size control, hot pressing, hot isostatic pressing and controlled atmosphere sintering [1–3]. However, it has been shown that lowering the density and introducing significant amounts of open po...
