摘要
从Goodier方程出发,研究了球形分散相周围基体中的形变能密度分布及其与分散相力学性能的关系,将所得结果结合前文给出的聚合物共混体的脆韧转变方程讨论了分散相的力学性能对聚合物共混体脆韧转变的影响,结果与实验一致。
From Goodier′s equations, the distribution of strain energy density in matrix around spherical dispersed phase and its relation with mechanical properties of dispersed phase were studied. Combining the calculated results with the brittle tough transition equation, the effect of the mechanical properties of dispersed phase on brittle tough transition of polymer blends was studied. The results are in agreement with the experiment.
