有限变形下含非完美界面复合材料有效模量的界限

UPPER AND LOWER BOUNDS OF EFFECTIVE MODULI FOR ELASTIC COMPOSITES WITH IMPERFECT INTERFACE AT FINITE STRAINS

导出了有限变形下含非完美界面两相复合材料的上下界限。在微小变形下，所导出的界限还原成已知的线性情况下的相应结果。数值上预示了非完美界面特性、有限变形对复合材料有效模量的影响规律，给出了与实际相符合的结果。

Upper and lower bounds of effective bulk and shear moduli for a twophase elastic composite with imperfect interface are derived in the case of finite strains. In the case of very small strains, these derived bounds reduce known results for linear cases. Numerical results predict effects of the features of imperfect interface and the strains on these bounds of the effective moduli of such composites, and give reasonable results.
