摘    要:为了研究用巴西试验测量PBX炸药间接拉伸强度的有效性,对PBX炸药进行了巴西试验和直接拉伸试验.结果表明,巴西试验测得的间接拉伸强度为3.60MPa,直接拉伸强度为5.50MPa,间接拉伸强度约为直接拉伸强度的65%.裂纹分析表明,巴西试验后PBX样品端面的初始开裂发生在中心点外,如偏心破坏,或者应力集中区的破坏,不满...

Abstract:In order to investigate the effectiveness of indirect tensile strength of PBX obtained by Brazilian test,Brazilian test and direct tension were performed.The results show that indirect tensile strength and tensile strength are 3.60MPa and 5.46MPa by Brazilian test and tension test to PBX samples respectively,and the former was about 65% of the latter.The analysis on the face cracks of PBX samples after Brazilian testing showed that initial cracking was out of the center of the PBX samples,maybe the off-cent...
