By using the improved self-consistent schemeproposed by Fan and carrying out a delicate mesoscop- ic analysisbased on a shear-lag model, the size effects including the thicknessof hard and soft layers relative to the inclusion dimension areobtained on the overall elastoplastic responses of materials up to 50cycles. The dominant characteristics of the analysis are that thecharacteristic dimension of a microstructure such as The thickness ofthe layers and the inclusion dimension can be explicitly incorporatedinto the formulation.展开更多

Rev. E 80 011144]. In this paper, the scaling analysis and the classical self-consistent mode-coupling approximation are utilized to investigate the dynamic scaling behaviour of the KPZ equation with memory effects. The values of the scaling exponents depending on the memory parameter are calculated for the substrate dimensions being 1 and 2, respectively. The more detailed relationship between the scaling exponent and memory parameter reveals the significant influence of memory effects on the scaling properties of the KPZ equation.展开更多
