An Analytic Solution to Large Deflection Displacement of Orthotropic Shallow Shells with Simply-Supported at Diagonal Sides and Free at Other Ones

There are three difficult problems in solving a large deflection displacement of orthotropic shallow shells with such boundary conditions as simply supported at some diagonal sides and free at other diagonal sides. They are:finding test functions that satisfy all the boundary conditions;treating non linear term of differential equations;making functions of every term density. An analysis and research about these problems is made and an effective solution is presented in this paper.Some ideal results are obtained by applying this method.
