拓扑约束 meaning in English
topological constraint
Examples
- To completely avoid producing elements jointed at their corner nodes and checkerboard patterns , which frequently occur when the topology optimization of plane continuum is studied , the theory of topology analysis of plane continuum in topology optimization process and the simple algorithm for programming are studied . according to algebraic topology theory , the boundary of elements and plane continuum are operated as a one - dimensional complex . by use of the adjacency vector in graph theory , the structural topology is described and the topological operation is achieved on a computer . by above , the structural topological feature in the evolutionary process is gained . these methods are effcient and reliable . under topology constraints , according to the results of stress analysis , by deleting elements and moving nodes at the boundary , more satisfactory results can be gained by using a few numbers of elements and iterations . to demonstrate the efficiency of these methods , solutions including some well - known classical problems are presented
