Introduction
The development of pulsed, non-destructive high-field magnets requires the advancement of conductor materials used as magnet windings [1–3].
The conductor materials are expected to have excellent combination of the mechanical strength and electrical conductivity.
In general, Cu-based composites prepared by drawing deformation are the promising conductor materials used in high-field magnets due to their high strength and electrical conductivity [4–6].
The starting materials were electrolytic copper of the purity higher than 99.95wt.% and commercial Fe and Ag of the purity higher than 99.70wt.%.

In recent years,with the economical development,society progress and the national economy fast
continual development,the dangerous material transport increased day after day,our country
dangerous goods transport security control faced with new challenge.Progressive dangerous goods
transport to the cities,the crowd threat is more and more important,so the dangerous material
transport security problem obtained the more and more high value.But until now,there is no research
on the dangerous goods transport.Dangerous material transport has big risk,high security request,the
social effect of accident and the property lost ale extremely serious,therefore find a way of the
dangerous material transport safety control,improve the environment of the dangerous material
transport,make he dangerous material transport develop safety and healthy,has become the transport
management department and the dangerous material transport profession important
topic.Therefore,the analysis of safety

This SOLID element is defined by eight nodes and the isotropic material properties, and is capable of cracking in tension and crushing in compression that is very suitable to model the brittle and quasi-brittle materials.
Stress Distribution in Mid-Pointed Arches According to experimental tests on masonry materials, tensile stresses play an important and critical role in the masonry arches (Toker and Unay 2004, Drysdale et al. 1994, Brick masonry arches introduction 1995).
