WebThis paper develops a two-scale asymptotic homogenization method for periodic composite Kirchhoff plates. In this method, a three-dimensional (3D) periodic plate problem is simplified as a Kirchhoff plate problem, which is governed by a fourth-order uniformly elliptic partial differential equation (PDE) with periodically oscillating coefficients. Then, a … Web也就是基于 Kirchhoff 计算假定的应用弹性力学的薄板问题的建模。 特别地，这次会从真实结果出发，反推应用弹性力学的简化建模是否合理。 一、从真实结果出发，深入解读 Kirchhoff 计算假定：
