Abstract:

The uniaxial compressive strength and the yield strength as determined by confined triaxial compression uniaxial strain of Composition B were found to be increased by changes in processing conditions and composition. In addition, Youngs modulus slope of the linear portion of the stress versus strain curve was also increased by the same changes. The uniaxial compressive strength and modulus were also found to depend on the position in the cast from which samples were taken for some casts. The results to date suggest that these effects are due primarily to changes in porosity and further that the changes in porosity are due to changes in processing conditions. Therefore, significant increases in strength and modulus may be accomplished by changes in processing conditions. The differences in the strengths of Composition B and TNT are also considered.
