Kulessa等人(2014年)在研究海冰对拉森C冰架(LCIS)结构完整性的影响的论文中认为,冰速度矢量与冰架中任何一点的第一主应力方向之间的角度-应力流角-可以用作“判断冰架稳定性的一阶标准”。虽然我们无法在Kulessa等人(2014年)或随后使用该度量的任何论文中找到应力流动角的精确数学定义,但从他们的描述中似乎可以合理地得出结论,可以计算为cos u= u· P1 u P1
In their paper examining the impact of marine ice on the structural integrity of the Larsen C Ice Shelf (LCIS), Kulessa and others (2014) argue that the angle between the ice velocity vector and the direction of the first principal stress at any point in an ice shelf–the stress-flow angle–can be used as a ‘first-order criterion on which to judge an ice-shelf’s stability’. While we have not been able to find an exact mathematical definition of the stress-flow angle in Kulessa and others (2014), or in any of the papers subsequently using this metric, it appears reasonable to conclude from their description that it can be calculated as cos u= u· P1 u P1
