Hybrid Frp-Concrete Railway Sleeper, Wahid Ferdous, Amar Khennane, Obada Kayali Sep 2013

Hybrid Frp-Concrete Railway Sleeper, Wahid Ferdous, Amar Khennane, Obada Kayali

Wahid Ferdous

The aim of this research was to investigate the feasibility of a hybrid FRP-concrete beam as a rail sleeper. It was hoped that the new design would overcome some of the sustainability issues associated with traditional sleepers. The hybrid system consisted of a Rectangular Hollow Section (RHS) pultruded profile filled with geo- polymer concrete. The specimens were tested in a four-point bending setup to determine the flexural properties such as the bending modulus (E) and modulus of rupture (MOR). It was found that the proposed composite beam satisfied the minimum flexural requirements for composite railway sleepers as stated in the …

Efectul Confinării Asupra Conlucrării Betonului Autocompactant Cu Armătura, Marian Sabau Aug 2013

Efectul Confinării Asupra Conlucrării Betonului Autocompactant Cu Armătura, Marian Sabau

Marian Sabau

Prezenta lucrare aduce contribuții legate de fenomenul de aderenţă dintre betonul autocompactant şi armătură. Principalul obiectiv al programului experimental a fost studierea fenomenului de aderenţă dintre betonul autocompactant şi barele de armătură, mai precis a efectului confinării betonului cu armătură transversală, pentru validarea sau îmbunătăţirea modelelor teoretice existente.

Studies Of Dynamic Crack Propagation And Crack Branching With Peridynamics, Youn Doh Ha Ph.D., Florin Bobaru Ph.D. Jul 2013

Studies Of Dynamic Crack Propagation And Crack Branching With Peridynamics, Youn Doh Ha Ph.D., Florin Bobaru Ph.D.

Florin Bobaru Ph.D.

In this paper we discuss the peridynamic analysis of dynamic crack branching in brittle materials and show results of convergence studies under uniform grid refinement (m-convergence) and under decreasing the peridynamic horizon (δ-convergence). Comparisons with experimentally obtained values are made for the crack-tip propagation speed with three different peridynamic horizons.We also analyze the influence of the particular shape of themicro-modulus function and of different materials (Duran 50 glass and soda-lime glass) on the crack propagation behavior. We show that the peridynamic solution for this problem captures all the main features, observed experimentally, of dynamic crack propagation and branching, as well …
