Modelling in Science Education and Learning, 2009 Els elements finits actualment constitueixen una eina fonamental per a resolució d’equacions diferencials en contextos reals. En aquest article presentem un bon exemple per al mètode: l’obtenció dels modes de ressonància sobre la tapa harmònica d’una ...

Modelling in Science Education and Learning, 2013 The mathematical model's validity used in computer programs are based on a specific formula implemented leading commercial software. Since these programs use their own databases of materials sometimes the question arises of what the miscalculation in ...

The interphase finite element [PDF]
Computational Mechanics, 2011 Mesomodelling of structures made of heterogeneous materials requires the introduction of mechanical models which are able to simulate the interactions between the adherents. Among these devices is quite popular the zero thickness interface (ZTI) model where the contact tractions and the displacement discontinuities are the primary static and kinematic ...

Desenvolupament virtual de producte
Temes de Disseny, 2002 Avaluar la funcionalitat, la seguretat, la qualitat, etc. d'un producte, pot ser llarg i costós. Els prototipus i els assaigs reals són eines determinants, però el seu ús exhaustiu en la fase de creació del producte pot encarir aquest procés i retardar ...

Triangular Elements in the Finite Element Method [PDF]
Mathematics of Computation, 1970 For a plane polygonal domain Ω \Omega and a corresponding (general) triangulation we define classes of functions p m ( x , y ) {p_m}(x,y) which are polynomials on each triangle and which are in ...

Journal of Approximation Theory, 1984 AbstractThe origin of this paper is the need for methods of solving the so-called altimetry-gravimetry problem of physical geodesy (see Svensson [7]) numerically. In the spherical approximation this problem leads to a pseudodifferential equation on a sphere, involving an invariant (with respect to the Riemannian geometry of the sphere ...

Applied Numerical Mathematics, 2015 We present an explicit and efficient way for constructing finite elements with assigned gradient, or curl, or divergence. Some simple notions of homology theory and graph theory applied to the finite element mesh are basic tools for devising the solution algorithms.
