The cross-section curvature ductility ratio for R.C inequiaxial T-shaped, L-shaped and cress-shaped columns is calculated by numerical method.

摘要采用非线性全过程数值分析方法，计算了钢筋混凝土不等肢T形、L形和十字形柱截面模型在多种工况下的截面曲率延性比。

The Distinct Element Method(DEM)is a discontinuum-based numerical method especially applicable to solve the discontinuity problems in jointed rock mass.

离散元法是基于不连续性假设的数值方法,它特别适合于求解节理岩体中的非连续性问题。

To overcome these problems, some numerical methods were developed, such as the subcell and nonuniform grid method, to handle the small feature size.

因此便有一些数值方法的提出来克服这些问题，比如次网格法和非均匀网格法。
