Effect of Friction and Material Compressibility on Deformable Modeling of Human Lung the coefficient of friction and Poisson’s ratio increases. However, Poisson’s ratio has more effect in models without contact surfaces where the average error changes from 0.33(±0.11) cm to 0.26(±0.07) cm as the Poisson’s ratio increased from 0.35 to 0.499.作者: neurologist 時(shí)間: 2025-3-22 04:08
