スポット溶接構造の公称構造応力算出法における分担荷重成分による主応力の分離法

抄録

In this study, a method for separating the value of the nominal structural stress, which was obtained by the nominal structural stress calculation method, on the value of each general loads component of nugget has been proposed. Since the stress and displacement of the circular plate by peeling load is the axis of symmetry, the boundary displacements are constant in the circumferential direction. Boundary displacement caused by the torsion is only a circumferential component, which is a constant value. Focusing on these viewpoints, the value of the nominal structural stress was separated values for each general loads. The proposed method was applied to the LP model, which is a spot welded structure. As a result, the usefulness of this method has been confirmed.
