i,m working with ansys , kindly specify what type of elements can be used for air craft wing for finding the centre of pressure and resulting stress due to lifting forces , the element connectivity requirements for the stringers ,spars and wings

RE: please define the following

I don't believe you will able to solve the problem in one step.  I'm not an expert in aerodynamics, but it seems you will have to run FlOTRAN first (the ansys fluids package) to determine the pressure distribution across the wing surface.  The pressure distubution can then be applied to your structural model composed of beam44 or beam189 elements for the spars and stringers, and shell63 elements for the sheet metal panel componets of the wings.
