Material Response Studies (MARS I). Volume 3: Development of Multiaxial Stress High Strain Rate Techniques

Abstract

Results are reported on the development of techniques to determine material yield and/or fracture under multiaxial stress loadings at strain rates to 100/second. An evaluation of various methods of biaxial and triaxial loading was made in order to determine a suitable method of testing both structural and ablator materials. Hence, the loading method and tubular specimen configuration are for nonhomogeneous, nonisotropic, brittle materials as well as more conventional ductile metals. A Biaxial Strain-Rate Machine has been built and some preliminary tests conducted. Details of the design and instrumentation are presented as well as preliminary data on an aluminum alloy.
