STATISTICS OF COMPRESSION AND SPALL STRENGTH OF A TUNGSTEN ALLOY

摘要：

Analysis of the effect of spatial variability on the shock response of a tungsten heavy alloy in compression and tensile states as determined from multi-point measurements shows that the heterogeneity of the material does not appear to affect the uniform deformation of the alloy under compression.However,tensile state and in consequence the spall strength reflect the heterogeneous characteristics possibly due to generation of cracks and other defects.Further,the average spatial response of the alloy is well represented by the conventional single point measurement.
