主 题：quasi-conforming method isogeometric analysis non-uniform rational B-spline EulerBernoulli beam exact geometry
摘 要：The problem of quick analysis using exact geometry data was proposed by Hughes et *** the isogeometric analysis framework was introduced as a *** this letter,the exact geometry concept is combined into the quasi-conforming framework and a novel method,i.e.,the exact geometry based quasi-conforming analysis is *** present method the geometry is exactly described by non-uniform rational B-spline bases,while the solution space by traditional polynomial *** method combines the merits of both isogeometric analysis and quasi-conforming finite element *** this letter Euler-Bernoulli beam problem is solved as an example and the results show that the present method is effective and promising.
