摘要 在夹层梁脱层分析所得到的附加状态的多项式解的基础上 ,提出了计算夹层梁脱层问题的能量释放率的一种简便方法 ,为此类问题的断裂力学分析提供了一种有力的工具。 By the polynominal resolution of sandwich beam at additional state, a simplified method of calculating the energy release rate is proposed,and this method is a powerful tool for analyzing such fracture mechanics problems.
