剪切带斑晶maxwell体有限元数值模拟太行山 - Numerical viscoelastic modeling for porphyroclast rotation in ductile shear zones is done by a viscoelastic finite element program based on detailed investigation to three ductile shear zones , the taihangshan mountains , north china . in this model porphyroclast garnet is assumed as isotropic elastic material with small elastic deformation , while the matrix quartz , feldspar as viscous fluid maxwell material which has increasing deformation with time . the viscosity of matrix is supposed to be 10
采用粘弹性力学分析程序对太行山阜平地区剪切带中斑晶旋转问题进行了有限元数值模拟。在计算模型中假定：石榴石斑晶为弹性材料，在应力作用下只产生很小的弹性变形石英长石质的基质部分为粘弹性材料，它具有随时间变形不断增大的特性。
