| Abstract: | An experimental investigation was carried out for the nonproportional cyclic properties of pure aluminum under four strain paths and two axial stress torsional shear strain combined paths. For the material of pure aluminum, the evolution characteristics of plastic strain rate direction and of plastic modules under these nonproportional strain paths were investigated, and the multiaxial ratchetting behavior was analyzed under these multiaxial stress strain combined paths. Some experimental results were obtained. |
