| Abstract: | The governing equations for deflections of elastic thin-plates induced by non-uniform surface stresses together with the boundary conditions are presented. By a physical analogue, the solution of the problem is equivalent to that for deflections of elastic plate induced by thermal stresses. Utilizing this method, the phenomena of local bending observed in experiments can theoretically be explained. |
