compressive yield stress and concentration for different flocculant dosage 有关学者提出同一材料的压缩屈服应力与体积分数具有相应的数学模型[18, 22],据此将实验数据进行线性拟合得浓密机全应力范围内压缩屈服应力随体积分数变化规律如图8,不同絮凝剂单耗情况下,压缩屈服应力随体积分数变化规律一致,都呈幂函数及指数函数复合增长.体积分数38%~42%为全尾砂脱水阻力突变起始区域,即体积分数大于该区域,压缩屈服应力迅速上升,表明若获得较高体积分数,则必须提供较大的压力,重塑絮团网状结构. 图8 不同絮凝剂单耗压缩屈服应力与体积分数拟合曲线 Fig. 8 Fitting curves between compressive yield stress and concentration......

Article ID: 1003-6326(2005)02-0414-05 Influences of post-annealing and internal stress on magnetoresistance properties of Ni80Fe20 films GAO Yan-qing(高艳清), WU Ping(吴 平), CAI En-jing(蔡恩静... 450℃. The internal stress in the films deposited on K9 glass is compressive and the resistance measurement shows that RM∥ is larger than RM⊥ in these films. However, in the films deposited at the same......
layer would yield based on the elastic-plastic evaluation, then the residual stress after shot peening can be achieved. The influence of initial welding residual stress on the stress distribution after... layer would be increased. Welding residual tensile stress can enlarge the thickness of the compressive stress layer at the same shot velocity when reverse yield appeared.关键词:......
