The purpose of this study is to develop an algorithm and a shell model that utilizes the advantages of HPM, for material nonlinear large displacement analysis using the shell model. First, the displacement field represented by the local coordinate system, which is different for each element, is converted into the local coordinate system of one of the adjacent elements. Subsequently, it is converted into the coordinate system of the element boundary edge. Finally, we propose a method to calculate the relative displacement from the displacement of the boundary edge of the adjacent elements obtained in this manner. In this study, we propose a numerical algorithm of material nonlinear large displacement analysis method using flat plate shell elements in HPM. First, we describe the flat plate elements of HPM using the local coordinate system. Even with a flat plate, adjacent elements have an angle when a large displacement occurs. Next, we propose the relative displacement in this case. The "step by step method" is used as the algorithm for large displacement analysis. Finally, the accuracy of the solution of the proposed method is verified by a simple numerical examples.
