Design of Compliant Structural Mechanisms Using B-Spline Elements

Volume 2: 31st Computers and Information in Engineering Conference, Parts A and B, 2011
Structural 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.

Efficient Power Conservation Mechanism in Spline Function Defined WSN Terrain

IEEE Sensors Journal, 2014
Coverage is a vital issue that ensures that basic functions are available in wireless sensor networks (WSNs). These functions provide communications during emergency rescue or in war environments. Sensor nodes must be dispersed and survive in place for a long time in order to accurately monitor all events.

Mechanically based design: adaptive refinement for B-spline finite element

Proceedings International Conference on Shape Modeling and Applications, 2002
This 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.

Simple spline-function equations for fracture mechanics calculations

International Journal of Fracture, 1979
The 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-

Spline-Based Finite Element Analysis in Composite Laminates Mechanical Properties

Applied Mechanics and Materials, 2011
The geometric parameters of the composite laminate in the engineering structure tend to have random properties. It is of great significance on how to study sensitivity of random parameters of laminated plates and carry on the optimized analysis to the parameteranalys when accurately estimating the reliability of structural design.

Selection of B-Spline Degree on Optimal Design of Mechanism

Advanced Materials Research, 2013
The 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 ...

New B-Spline Finite Element approach for geometrical design and mechanical analysis

International Journal for Numerical Methods in Engineering, 1998
The main idea of this paper is to integrate a mechanically based geometrical design concept with the mechanical analysis module in a uniform \(B\)-spline finite element (BSFE) environment. We formulate the BSFE method and verify its validity and adequacy for linear elastic rod and plate models. In particular, we demonstrate the feasibility of applying \

Modeling respiratory mechanics in the MCAT and spline-based MCAT phantoms

IEEE Transactions on Nuclear Science, 2001
Respiratory 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 ...
