This paper deals with an adaptive refinement technique of a B-spline degenerate shell finite element model, for the free vibration analysis of curved thin and moderately thick-walled structures. The automatic refinement of the solution is based on an

Within the context of structural dynamics, Finite Element (FE) models are commonly used to predict the system response. Theoretically derived mathematical models may often be inaccurate, in particular when dealing with complex structures. Several pap

A B-spline based FE model updating procedure is proposed. The approach is based on the least squares minimization of an objective function dealing with residues, defined as the difference between the model based response and the experimental measured

This paper presents a Point Based (PB) spline degenerate shell finite element model to analyze the behavior of thin and moderately thick-walled structures. Complex shapes are modeled with several B-spline patches assembled as in conventional finite e

This work considers the fitting of data points organized in a rectangular array to parametric spline surfaces. Point Based (PB) splines, a generalization of tensor product splines, are adopted. The basic idea of this paper is to fit large scale data

This paper presents a method to obtain the mathematical model of a free-form curve or a surface fitting a set of point coordinates by a rational B-spline (NURBS) formulation in the homogeneous R 4 space. A method to evaluate the control points R 4 co
