摘要
根据两种高聚物粘结炸药在不同温度 (- 10～ 4 5℃ )和应变率 (10 - 6～ 10 - 4 s- 1 )下的准静态拉伸实验结果 ,建立了考虑温度和应变率效应的非线性本构关系。理论预测与实验结果吻合 ,为这类材料的力学性能分析提供了依据。
Based on the experimental data from quasistatic tension of two polymerbouded explosives (PBX) under temperature from -10 ℃ to 45 ℃ and strain rate from 10 -6 s -1 to 10 -4 s -1 ,a nonlinear constitutive relation is proposed to describe the mechanical behaviors of the said PBX under the simple tension at different temperature and strain rate. The theoretical prediction from the constitutive relation is well agreeable to the experimental results,which provides a basis for analyzing the mechanical response of this kind of material construction.
