【Abstract】 The paper gives the normalized loads for 4 kinds of components in common use. The components are: simply supprted beams and plates, pure bending beams and plates, tri point bending arched beams and arched plates, and semi ring shaped curve bars and plates. At the same time, the paper gives the J integration computational formula as well as the needed data in widened interval of strain hardening exponent.更多还原
