Modeling of interfaces in two-dimensional problems using solid finite elements with high aspect ratio
(Pergamon-Elsevier B.V. Ltd, 2012-03-01)
The use of standard solid finite elements with a very high aspect ratio is proposed to model the behavior of thin interface regions between distinct components of composite structural members. It is shown that these elements ...
A finite strain, finite band method for modeling ductile fracture
(Elsevier, 2012-02)
We present a finite deformation generalization of the finite thickness embedded discontinuity formulation presented in our previous paper [A.E. Huespe, A. Needleman, J. Oliver, P.J. Sánchez, A finite thickness band method ...
Shell curvature as an initial deformation: A geometrically exact finite element approach
(JOHN WILEY & SONS LTD, 2009)
An alternative approach for the analysis of arbitrarily curved shells is developed in this paper based on the idea of initial deformations. By `alternative` we mean that neither differential geometry nor the concept of ...
Poset splitting and minimality of finite models
(Academic Press Inc Elsevier Science, 2018-07)
We prove that the fundamental group and the integral homology groups of a poset with fewer than 13 points are torsion free, settling a conjecture of Hardie, Vermeulen and Witbooi and answering a question of Barmak. In ...
3D concurrent multiscale model for crack propagation in concrete
(2020-04-01)
A new approach for concurrent multiscale modeling of three-dimensional crack propagation in concrete is proposed. A macroscopic model with homogenized elastic parameters is adopted in the regions where the material behaves ...
A mixture theory based method for three-dimensional modeling of reinforced concrete members with embedded crack finite elements
(Techno-Press, 2008-12)
The paper presents a methodology to model three-dimensional reinforced concrete members by means of embedded discontinuity elements based on the Continuum Strong Discontinuous Approach (CSDA). Mixture theory concepts are ...
Semiclassical scaling functions of sine-Gordon model
(Elsevier B.V., 2004-11-08)
We present an analytic study of the finite size effects in sine-Gordon model, based on the semi-classical quantization of an appropriate kink background defined on a cylindrical geometry. The quasi-periodic kink is realized ...
