本成果不仅可用于航天产品先进复合材料结构和时效分析 (如固体火箭发动机缠绕壳体与弹翼 ) ,而且可用于普通复合材料和结构分析 ,如建筑、机械、压力容器 ,特别是航空结构 ,飞机在飞行一定周期后 ,确定其剩余寿命。本成果创造性地利用剩余刚度预报剩余强度和寿命 ,建立了剩余 This result can be used not only for the advanced composite structures and aging analysis of aerospace products (such as solid rocket motors wound shells and wings), but also for general composite materials and structural analysis such as construction, machinery, pressure vessels, especially aeronautical structures, The aircraft after a certain period of flight, to determine the remaining life. This result creatively uses the residual stiffness to predict the residual strength and life span and establishes the surplus
