This paper presents the results of a study on the multiaxial behavior of a high explosive. Measurements were obtained using biaxial tension, tension, and compression loadings; three-point bend, shear, and diametral compression tests; and a channel-die experiment. Strains were determined by image correlations. A secant elastic constitutive law was used to determine missing out-of plane strains and stresses. Measured and estimated data were then compared to the Rankine and Mohr−Coulomb criteria and a previously published threshold for this material.
