A new extension of the Applied Element Method (AEM) for structural analysis is introduced. This paper deals with the large deformation of structures under dynamic loading condition. As no geometric stiffness matrix is adopted, the formulation used for large deformation is simple and it can be applied for any structural configuration or material type. A new technique based on determining the residual forces due to geometrical changes is proposed. The accuracy of this technique is verified in small deformation range by eigen value analysis. In large deformation range, the collapse behavior of structures and the rigid body motion of the failed structural elements can be followed accurately.
