Modeling and analysis of stiffened panels are two key technologies in the design of
aerospace thin-walled structures. For the stiffened panels with complex geometry, classical …

In the aerospace field, there are numerous assembled thin-walled structures with complex
geometric continuity conditions. This makes isogeometric analysis (IGA) inevitably meet …

The article is aimed to provide an effective digital solution in support of the infill
microstructural design within objectives generated from normal computer aided design …

Inspired by the r-refinement method in isogeometric analysis, in this paper, the authors
propose a curvature-based r-adaptive isogeometric method for planar multi-sided …

Toric surface patches are a class of multi-sided surface patches that can represent multi-
sided domains without mesh degeneration. In this paper, we propose an improved …

The legacy of master builder Félix Candela is cemented by his widespread adoption of thin
hyperbolic paraboloid (hypar) umbrellas within architecture across the Americas. Exhibiting …

Generalized Bézier surfaces are a multi-sided generalization of classical tensor product
Bézier surfaces with a simple control structure and inherit most of the appealing properties …

Abstract The Geometry-Independent Field approximaTion (GIFT) technique, an extension of
isogeometric analysis (IGA), allows for separate spaces to parameterize the computational …
