Numerical analysis approach for stamping edge split of high strength steel considering sheared burr effect 考虑剪切毛刺影响的高强钢冲压边部破裂缺陷数值分析方法
In the procedure of mesh optimization, three optimization operators edge split, edge collapse, edge swap are used; and a local spherical surface is defined to interpolate the given mesh surface. 在优化过程中采用了三种优化算子(边分裂、边消除、边替换),是一个简单的曲面网格优化的通用算法。
Subdivide - Each selected edge is split in two, new vertices are created at middle points, and faces are split too, if necessary. 细分-每个选择的边一分为二,新的顶点将创建在边的中心;面也是一分为二。
Further a slope stability model is established by the edge condition of split trailing and soft layer in loess bottom. 论文进一步建立了考虑黄土后缘拉裂和底部有软弱下卧层的边坡稳定性计算模型。
Topological simplification can provide better simplification in the progressive mesh, but all current progressive mesh ( PM ) representations do not support topological simplification, and edge collapse and vertex split operator may create non-manifold. 拓扑简化可以为渐进网格带来更好的效果,但目前几乎所有的渐进网格方法都不支持拓扑简化,而且EdgeCollapse和vertexsplit操作有时会产生非流形。
