Abstract:以 AA5182 铝合金两次非线性加载的应变极限变化为研究对象, 考虑板材的各向异性, 分别进行了不同轧制方向的单向拉伸预变形和等双向拉伸预变形, 并测定了材料在二次非线性加载路径下基于应变的成形极限曲线 (FLC)。结果表明,基于应变的 FLC 与加载路径相关, FLC 形状随加载路径变化; 将测定的应变值经数值变换, 获得了基于应力的成形极限图(FLSD) 和基于极坐标等效塑性应变成形极限图模型 (PEPS-FLD)。通过不同的加载路径, 验证了两种极限模型均可以描述复杂加载条件下的成形极限预测。 FLSD 和 PEPS-FLD 模型具有路径无关性, 不同应变路径下的曲线接近重合。
