Abstract:
A methodology is presented which enables isogeometric analysis on trimmed NURBS surfaces. The general limitations of NURBS-based isogeometric analysis are roughly delineated to resolve the associated issues. A local reconstruction technique using a geometric basis is developed and applied to evaluate the finite element constituents of the trimmed knot spans in terms of the underlying control variables. This paper covers the algorithmic treatment of single patches as well as of multi-patches. Mor...     »
