damping viscosity meaning in English

阻尼粘性

The node force corresponding to damp was used to control the mesh distortion . numerical studies show that the method proposed by this paper can successfully control the severe distortion of mesh and retain the density of elements during the membrane form - finding when the damp viscosity coefficient is in a limited scale . especially this method can avoid the sparseness of mesh in the location of lower curvature and have good convergence characteristic
同时针对找形分析中的动力松弛格式，本文提出了全新的控制网格变形的动力松弛法，此方法能够有效地解决膜结构找形分析中网格的大变形问题，克服了在曲率较小处网格过于稀疏的缺陷，在曲率较小处保证了单元的密度和初始构形的精度，并且收敛性较好，为准确进行荷载分析和裁剪分析奠定了基础。
