When we analyze finite element structures with extremely large deformation, non-linear problems are caused by not only geometrical characteristics of an element but also elements or nodes contact phenomena. Contact problem is a complex non-linear case and it is important to consider how to express the phenomena using digitalized data. There are numerous types of contact phenomena that are adoptable in finite element analyses. For example, node-node contact, node-element contact, node-surface contact, etc. From geometrically non-linearity of an element and the limitation of segment elements size make the contact problem is extremely difficult to solve. The main objective of this study is to apply Tangent StiffnessMethod for simulation of a non-friction contact phenomenon between nodes and elements. Furthermore, by adding some alteration to the contact judgment, various types of structures can be applied to perform contact analysis.
