Selection of B-Spline Degree on Optimal Design of Mechanism
Advanced Materials Research, 2013The degree is an important parameter for B-spline. In this paper, as one example of optimal design in mechanism, the optimal design of the cam curve to control the residual vibration of the follower output for an indexing cam mechanism is taken and the effect of the degree of the B-spline to describe the cam curve on the optimization performance is ...

Mechanically based design: adaptive refinement for B-spline finite element
Proceedings International Conference on Shape Modeling and Applications, 2002This paper presents a method for adaptive refinement within an integrated mechanically based CAE system. The system uses a mechanical B-spline finite element model for both geometric design and mechanical analysis. A technique for locally refining a solution by B-spline finite elements is presented.

Mechanically based models: Adaptive refinement for B‐spline finite element
International Journal for Numerical Methods in Engineering, 2003AbstractThis article presents two new methods for adaptive refinement of a B‐spline finite element solution within an integrated mechanically based computer aided engineering system. The proposed techniques for adaptively refining a B‐spline finite element solution are a local variant of np‐refinement and a local variant of h‐refinement.

B-spline method for energy minimization in grid-based molecular mechanics calculations
Journal of Computational Chemistry, 1998A method is described for molecular mechanics calculations based on a cubic B-spline approximation of the potential energy. This method is useful when parts of the system are allowed to remain fixed in position so that a potential energy grid can be precalculated and used to approximate the interaction energy between parts of a molecule or between ...

Simple spline-function equations for fracture mechanics calculations
International Journal of Fracture, 1979The paper presents simple spline-function equations for fracture mechanics calculations. A spline function is a sequence of piecewise polynomials of degree n greater than 1 whose coefficients are such that the function and its first n-1 derivatives are continuous. Second-degree spline equations are presented for the compact, three point bend, and crack-

Design of Compliant Structural Mechanisms Using B-Spline Elements
Volume 2: 31st Computers and Information in Engineering Conference, Parts A and B, 2011Structural design is an inverse problem where the geometry that fits a specific design objective is found iteratively through repeated analysis or forward problem solving. In the case of compliant structures, the goal is to design the structure for a particular desired structural response that mimics traditional mechanisms and linkages.

Modeling respiratory mechanics in the MCAT and spline-based MCAT phantoms
IEEE Transactions on Nuclear Science, 2001Respiratory motion can cause artifacts in myocardial SPECT and computed tomography (CT). The authors incorporate models of respiratory mechanics into the current 4D MCAT and into the next generation spline-based MCAT phantoms. In order to simulate respiratory motion in the current MCAT phantom, the geometric solids for the diaphragm, heart, ribs, and ...
