... for the specification of heterogeneous objects. In this research, we provide an intuitive way to model the object heterogeneity by using only a few parameters. These parameters carry physical meanings, such as diffusion coefficients in the diffusion process. We use a B-spline representation to model heterogeneous...

... Using one single trimmed B-Spline surface to fill an n-sided hole is a much desired operation in CAD, but few papers have addressed this issue. The paper presents the method of using trimmed B-Spline surfaces to fill n-sided holes based on energy minimization or variational technique. The method...

... Designing B-Spline Surfaces is difficult and cumbersome with traditional 2D based interfaces, e.g., a 2D mouse. Based on energy minimization or variational surfacing technique, the paper presents a technique for using a haptic device to design B-Spline surfaces. In our system, a haptic interface...

Paper No: DETC2011-47168
... This paper examines the limitations of using B-spline representation as an analysis tool by comparing its geometry with the nonlinear finite element absolute nodal coordinate formulation (ANCF) geometry. It is shown that while both B-spline and ANCF geometries can be used to model non-structural...
