Integration of geometric design and mechanical analysis using B-spline functions on surface
International Journal for Numerical Methods in Engineering, 2005AbstractB‐spline finite element method which integrates geometric design and mechanical analysis of shell structures is presented. To link geometric design and analysis modules completely, the non‐periodic cubic B‐spline functions are used for the description of geometry and for the displacement interpolation function in the formulation of an ...

New B-Spline Finite Element approach for geometrical design and mechanical analysis
International Journal for Numerical Methods in Engineering, 1998The 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 \

Mechanisms of wear in misaligned splines
Tribology, 1968Experimental results are presented on the wear behavior of misaligned splines operating without lubrication and with either grease or oil lubrication, in various environmental atmospheres. On the basis of the observed results, it appears that protection from rapid wear stems from conditions which inhibit oxidation of the stressed metal surfaces.

A spline wavelet finite‐element method in structural mechanics
International Journal for Numerical Methods in Engineering, 2005AbstractThe wavelet‐based methods are powerful to analyse the field problems with changes in gradients and singularities due to the excellent multi‐resolution properties of wavelet functions. Wavelet‐based finite elements are often constructed in the wavelet space where field displacements are expressed as a product of wavelet functions and wavelet ...

Space discretization by B-Splines on discontinuous problems in structural mechanics
Proceedings of the 7th Balkan Conference on Informatics Conference, 2015Elastic structures with material or geometrical discontinuities often appear among engineering applications. The appropriate usage of space discretization functions is essential for deriving mathematical models with sufficient accuracy. In the current work, a beam with stoppers is considered as an example of elastic structure with discontinuities.

AIP Conference Proceedings, 2016
Nowadays, full-field measurement methods are largely used to acquire the strain field developed by heterogeneous mechanical tests. Recent material parameters identification strategies based on a single heterogeneous test have been proposed considering that an inhomogeneous strain field can lead to a more complete mechanical characterization of the ...

Spline function approximation in discrete mechanics
International Journal of Non-Linear Mechanics, 1979It is shown that the fundamental equations in discrete mechanics are consistency relations for a parametric spline function approximation. The formula which relates displacement and acceleration is of O((Δt)2 and unconditionally stable in the sense of Dahlquist. This method is equivalent to two first order difference equations which relate velocity and
