On the behaviour of spherical inclusions in a cylinder under tension loads

Ingenius Vol. 19, 2018, pp. 69-78 S. Montero, R. Bustamante, A. Ortiz-Bernardin Abstract In the present paper the behaviour of a hyperelastic body is studied, considering the presence of one, two and more spherical inclusions, under the effect of an external tension load. The inclusions are modelled as nonlinear elastic bodies that undergo small strains….

A volume-averaged nodal projection method for the Reissner-Mindlin plate model

Computer Methods in Applied Mechanics and Engineering In press. A. Ortiz-Bernardin, Philip Köbrich, Jack S. Hale, Edgardo Olate-Sanzana, Stéphane P. A. Bordas, Sundararajan Natarajan. Abstract We introduce a novel meshfree Galerkin method for the solution of Reissner-Mindlin plate problems that is written in terms of the primitive variables only (i.e., rotations and transverse displacement) and…

Modal strain energy-based debonding assessment of sandwich panels using a linear approximation with maximum entropy

Entropy 2017, 19(11), 619 V. Meruane, Matias Lasen, E. López Droguett, A. Ortiz-Bernardin Abstract Sandwich structures are very attractive due to their high strength at a minimum weight, and, therefore, there has been a rapid increase in their applications. Nevertheless, these structures may present imperfect bonding or debonding between the skins and core as a result…
