摘要: 本文导出了包括各组成相尺寸因素在内的、用组成相材料断裂韧性和体积比来估计多相材料断裂韧性的表达式: 通过极限分析,导出了符合混合律的上限值表达式(n→∞) 和下限值表达式 其中V_f~j,K_(Ic)~j分别表示各相材料的体积比和断裂韧性,n是和各组成相尺寸有关的参数。
Abstract:The expressions for estimating fracture toughness of the polycomponent composite materials have been derived in terms of the fracture toughnesses and the volume fractions of individual component each is included. The expression, conformed to mixed rule, of upper (n→) or lower (n=1) bound value was also derived on the basis of limit analysis.
