HMX基散粒体与其代用材料的准静态力学等效性
Quasi-static Mechanical Equivalence of HMX-Based Granular Explosives and its Substitute Materials
摘要
Abstract
To investigate the quasi-static mechanical equivalence between HMX-based granular explosives(JO-8)and its substi-tute materials(Ba(NO3)2-based PBX and Na2SO4-based PBX),quasi-static compression experiments were conducted on three types of explosive column sample using a self-developed micro-compression testing apparatus.Parameters fitting was performed on the stress-strain curves obtained from the experiment based on the concrete constitutive model.To further evaluate the me-chanical equivalence between JO-8 and the substitute materials,quasi-static compression tests were performed on their internal crystalline single particles HMX,Ba(NO3)2,and Na2SO4.The results indicate that the quasi-static mechanical behavior of JO-8 explosive column is better characterized by the true stress-strain curve.The good agreement between the fitting data from the constitutive model and the experimental results verifies the effectiveness of the constitutive model.Based on the combined experi-mental results of the three types of explosive column and their internal single crystal particles,as well as the data analysis of the constitutive model,it reveals that Ba(NO3)2-based granular explosive exhibits mechanical properties comparable to JO-8 explo-sive under quasi-static compression conditions,compared with Na2SO4-based granular explosive.关键词
