报告摘要：

    This talk is concerned with the problem of two rigid inclusions closely spaced in an isotropic elastic thin plate. Under the linear elasticity for infinitesimal deformations and Kirchhoff-Love theory, this problem is formulated by a fourth-order elliptic Dirichlet boundary value problem. We establish upper bounds for the gradient and Hessian matrix of the solution when the boundary of the inclusions is $C^{3, \gamma}$. If the regions are smooth, we further obtain the upper bound estimates for the higher-order derivatives. The low bound estimate for the Hessian matrix is derived under some symmetric assumptions.
