利用双尺度收敛的工具,我们为Fleck和Willis (J. Mech.)得到的均匀化结果提供了一个严格的数学设置。理论物理。固体52(2004)1855- 1888)关于应变梯度复合材料的有效塑性行为。此外,从变形理论到流动理论,我们证明了在各向同性线性硬化存在下准静态演化均匀化的收敛结果。
Using the tool of two-scale convergence, we provide a rigorous mathematical setting for the homogenization result obtained by Fleck and Willis (J. Mech. Phys. Solids 52 (2004) 1855- 1888) concerning the effective plastic behaviour of a strain gradient composite material. Moreover, moving from deformation theory to flow theory, we prove a convergence result for the homogenization of quasistatic evolutions in the presence of isotropic linear hardening.
