On Plastic Deformation Capacity of Notched Plates
Yoshikazu MORIWAKI, Kenji HAYASHI
In order to establish the ultimate state design, it should be veri fied the mechanical properties of tension members as well as compression members in the ultimate state. In this paper, resting on this viewpoint, tension tests on notched plates were carried out to investigate the influence of mechanical properties of materials and stress concentration on the plastic deformation capacity, and to clarify the mecanical characteristics of tension members. And a practical formula is proposed to evaluate the plastic deformation capacity of tension members. Moreover, it is also clarified the parameter to control the plastic deformation fields of tension members in the ultimate state.
