| Abstract: | The paper makes tests on low cycle fatigue under nonproportional cyclic loading (nonproportional loading) in the condition of various strain paths and observes the microstructure of 316L austenitic stainless steel.Based on the combination of macroscopic experimental results with microscopic experimental results,the micromechanism of cyclic additional hardening under multiaxial nonproportional loading is studied deeply. |
