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.%.

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).
