In this research, geometrically exact contact calculation method for FEM using beam element is proposed. The proposed method discretely represents surface shape of beam by particles and imposes mechanical and geometric constraints of contact between particles. Since the particles and element nodes are geometrically related, the contact constraint conditions between the particles can be yielded into the equation of motion as the constraints defined between the elements. This approach allows to easily resolve geometrically complex contact configurations even if large and complex deformation such as torsion is occurred. Validity and usefulness of the proposed method is indicated by solving numerical examples of static or dynamic contact problems of beams.
