Numerical study of damaged micro-lattice blocks subjected to uniaxial compressive loading
(Elsevier, 2020-09)
This article presents a numerical study on the mechanical behaviour of damaged micro-lattice (ML) blocks submitted to uniaxial compressible loads. The numerical model is implemented in the commercial finite-element code ...
Design and construction of a transducer for bite force registration.
(ELSEVIER SCI LTD, 2009-05-29)
This study describes the development of a system for quantification of human biting forces by (1) determining the mechanical properties of an epoxy resin reinforced with carbon fiber, (2) establishing the transducer's ...
An H-Adaptive Unstructured Mesh Refinement Strategy for Unsteady Problems
(Planta Piloto de Ingeniería Química, 2009-12)
An h-adaptive unstructured mesh refinement strategy to solve unsteady problems by the finite element method is presented. The maximum level of refinement for the mesh is prescribed beforehand. The core operation of the ...
Surface diffusion of graphs: Variational formulation, error analysis, and simulation
(Society for Industrial and Applied Mathematics, 2004-12)
Surface diffusion is a (fourth-order highly nonlinear) geometric driven motion of a surface with normal velocity proportional to the surface Laplacian of mean curvature. We present a novel variational formulation for graphs ...
The distribution of factorization patterns on linear families of polynomials over a finite field
(Springer, 2017-10)
We estimate the number |Aλ| of elements on a linear family A of monic polynomials of Fq[T] of degree n having factorization pattern λ:=1λ12λ2nλn. We show that |Aλ| = T(λ)qn-m + O(qn-m-1/2), where T(λ) is the proportion of ...
Nonpositively curved metric in the positive cone of a finite von Neumann algebra
(Oxford University Press, 2006-08)
In this paper we study the metric geometry of the space Σ of positive invertible elements of a von Neumann algebra. A with a finite, normal and faithful tracial state T. The trace induces an incomplete Riemannian metric ...
Finite-dimensional pointed Hopf algebras over finite 3 simple groups of Lie type V. Mixed classes in Chevalley 4 and Steinberg groups
(Springer, 2020-06)
We show that all classes that are neither semisimple nor unipotent in finite simple Chevalley or Steinberg groups different from PSLn(q) collapse (i.e. are never the support of a finite-dimensional Nichols algebra). As a ...
Nonconforming Galerkin methods for the Helmholtz equation
(John Wiley & Sons Inc, 2001-09)
Nonconforming Galerkin methods for a Helmholtz-like problem arising in seismology are discussed both for standard simplicial linear elements and for several new rectangular elements related to bilinear or trilinear elements. ...
