To achieve this required three basic steps. The first step involved the study of Green’s function describing the vertical displacements of the surface of an elastic quarter-space due to vertical force applied on its surface. For this case, an explicit formula was obtained by analytically resolving a complicated integral that did not previously have an analytical solution. The second step involved the study of the coupled system of a plate and an elastic quarter-space. This portion focused on determining reactive forces in the contact zone based on Hetenyi’s solution. After determination of the reactive forces, certain features were attributed to the plate’s edges. The final step involved the application of Ritz’s method to determine the deflections of the plate resting on the surface of the quarter-space. Finally, an example calculation and validation of results are given. This is the first semi-analytical solution proposed for this type of contact problem.||Funding Details:||Not applicable||Type of material:||Journal Article||Publisher:||Elsevier||Journal:||International Journal of Solids & Structures||Volume:||47||Issue:||14-15||Start page:||1822||End page:||1829||Copyright (published version):||Crown Copyright 2010 Published by Elsevier||Keywords:||Deformable rectangular plate; Green’s function; Quarter-space; Contact problem; Ritz’s method||Subject LCSH:||Boundary value problems
