摘要
在简化模型的基础上,推导了复合固体推进剂中Ⅰ型拉伸裂纹的裂尖区域应力、应变与位移的关系式,并进行了粘弹性有限元方法分析。结果表明,有限元分析能获得具一定精度的结果,并与理论分析基本吻合。
Based on predigested model, the equation of stress, strain and displacements at the crack port of Ⅰ pulled crack in compound solid propellant was deduced in this paper. The analysis of the viscoelasticity finite element means was processed. The result showed that the finite element analysis could acquire the result with certain accuracy and was basically agreed with the theory analysis.
