The Advantage of Superposition Method and Numerical Modeling during Studying Elastic Thin Plate

In this paper,superposition method is applied to the study of the deformation of elastic thin plate with two fixed adjacent sides: one freelysupported side,the other free side under uniform pressure.Numerical modeling is applied,and the result is pointed to be a criterion.In order to guarantee the accuracy of the result of superposition method,the result is compared to the criterion.The advantage of them can be found when they are applied together.In practice,if superposition method can be applied by cooperating with numerical modeling,it will be very great.
