摘要
对纯铝材料进行了4 种应变路径和2 种轴向应力扭转剪应变组合路径的非比例循环试验,揭示了纯铝在非比例循环加载下塑性应变率方向和塑性模量的演化特征;分析了纯铝的多轴棘轮行为。
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.
