An enhanced unfolding Inverse Finite Element Method (IFEM) has been used together with an extended strain-based forming limit diagram (EFLD) to develop a fast and reliable approach to predict the feasibility of the deep drawing process of a part and determining where the failure or defects can occur. In the developed unfolding IFEM, the meshed part is properly fold out on the flat sheet and tre...

E-mail: [email protected] There is growing evidence that genetic and chromosomal factors are important in the genesis of autism spectrum disorders. The most commonly reported cytogenetic abnormalities are deletions involving chromosomes 7q, 22q13, 2q37, 18q, and Xp, as well as sex chromosome aneuplodies (47,XYY...

Two-layer metallic sheets have wide applications in aerospace, marine, automotive and domestic industries due to their superlative characteristics. In this paper, the formability of two-layer sheet is investigated through analytical, experimental and numerical approaches. An analytical model is developed based on Marciniak-Kuczynski method associated Hill’s non-quadratic yield criterion. Formin...

Abstract The purpose of this work is to predict and analyze the formability twinning – induced plasticity steels through Marciniak-Kuczynski (MK) theory with emphasis on solutions for improving prediction results. selected constitutive equations involve Yld00-2d Barlat et al. (2003) plane stress yield function, Swift strain–hardening power law dislocation density based model proposed by Kim (20...

Los estudios acerca de las élites y el perfil los gabinetes son muy vastos; sin embargo, pocos quienes han estudiado fenómeno desde una perspectiva com- parativa. En este artículo analizaremos Gobiernos con empresarial en América Latina durante período 2000-2019. Tomamos casos Mauricio Macri Argentina, Michel Temer Brasil Vicente Fox México; Sebastián Piñera Chile, Álvaro Uribe Colombia, Elías ...
