摘要
Abstract
Compressive mechanical properties were obtained and stress-strain plots were analyzed by means of uniaxial compression tests, which were performed at different strain rate ( 1/300 ~ 1/12 s-1 ) and temperature( -40~25 ℃ ) on HTPB propellant. The results show that compression stress and compression modulus increase gradually with decreasing temperature and increasing strain rate, and present linear-log function relation with strain rate ( and ) , which could be used to predict the compression mechanical properties at wide strain rate. In addition, the results of variance analysis indicate that low temperature has significant effect on compression modulus and compression strain,while strain rate has significant effect on compression stress.关键词
