Abstract:

Through the use of a modified diameter gage which measured the principal width and thickness strains independently, it was possible to obtain more basic property data in testing of sheet materials. Materials studied were H-11 die steel, Cr Mo tool steel, AMS 5548, AMS 5547, 34 hard 301 stainless steel and some alloyed and unalloyed titanium. Effects of heat treatment and low testing temperature on flow stress, fracture stress, fracture strain and strain hardening were evaluated. A limited study on mechanical anisotropy and true strain rate was also conducted. Author
