Experimental observation and computational simulation of dynamic void collapse in single crystal cooper
نویسندگان
چکیده
Hollow circular cylinders of single crystal copper are subjected to externally applied explosive loads that cause the collapse of the cylinder. Then numerical simulations are performed to understand the deformation process that leads to localized deformation and tensile cracking, observed in partially collapsed cylinders of fcc single crystals. The results of experiments and numerical simulations are in good agreement. © 1998 Published by Elsevier Science S.A. All rights reserved.

Effect of Wire Pitch on Capacity of Single Staggered Wire and Tube Heat Exchanger Using Computational Fluid Dynamic Simulation
Single staggered is a design development of normal wire and tube heat exchanger that wires are welded with staggered configuration on two sides. Capacity of wire and tube heat exchanger is the ability of the heat exchanger to release heat. The objective of this study is to analyse the effect of wire pitch (pw) on capacity of single staggered wire and tube heat exchanger. The research...
متن کاملNumerical Evaluation of Progressive Collapse Potential in Reinforced Concrete Buildings with Various Floor Plans Due to Single Column Removal
Progressive collapse is defined as the spread of an initial damage from one member to another, leading to extensive partial or total collapse of the structure. In this research, the potential of progressive collapse due to a sudden removal of vertical load-bearing elements in reinforced concrete buildings structures with different floor plans such as geometrical regular and irregular floor plan...

متن کاملStatic and dynamic axial crushing of prismatic thin-walled metal columns
In this paper, a novel approach is proposed to investigate the progressive collapse damage of prismatic thin walled metal columns with different regular cross sections, under the action of axial quasi-static and impact loads. The present work mainly focuses on implementation of some important factors which have been neglected in other studies. These factors include the effect of reducing impact...
