| 摘 要： | 测试了等静压和模压两种不同工艺成型的炸药件不同方向取样的力学性能,测试结果表明:在等静压炸药件不同方向上取样的拉伸和压缩强度没有明显差异,可以认为等静压炸药件的力学性能是各向同性的;对于模压炸药件,虽然不同方向取样的压缩强度没有明显差异,但是不同方向取样的拉伸强度却存在显著差异,因此,模压炸药件的力学性能并非是各向同性的,而是各向异性的。

| Abstract: | The mechanical properties of two types of specimens were tested,which were sampled from different direction(transverse and longitudinal) in two PBX formed by mould pressing and isostatic pressing respectively.The experimental results show that both of tensile and compressive strength between transverse and longitudinal directions in isostatic pressing PBX are almost the same,in other words,isostatic pressing PBX is mechanically isotropic;and although compressive strength between transverse and(longitudinal) does not show obvious difference for mould pressing PBX,but tensile strength shows apparent difference,mould pressing PBX is(anisotropic.) |
