（3）The influence of the size parameters of U-shaped corrugated sandwich plates and U-shaped folding sandwich plate on the response of sandwich plate  under load has been analyzed，and the structure of the excellent U-shaped corrugated sandwich plate and U-shaped folding sandwich panel have been put forward.

（4）On the basis of MATLAB software，a calculation interface of corrugated sandwich plate and U-shaped folding U-shaped sandwich plate has been developed through the GUI program. The interface can not only rapidly calculate the stiffness and response of the two kinds of sandwich plates, but also judge the rationality of the input parameters of the sandwich plate，which is an efficient tool for theoretical calculation of sandwich plate，and it also provides guidance for the calculation of other special structures in the form of sandwich.

Keywords: U-type corrugated sandwich plate; U-shaped folding sandwich panel; equivalent parameters; Response calculation; program development
