Ingenius Vol. 19, pp. 69-78, 2018 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.

Accepted Paper: Modal Strain Energy-Based Debonding Assessment of Sandwich Panels Using a Linear Approximation with Maximum Entropy

  • November 21, 2017
  • Comments off

Paper Accepted for Publication in Entropy V. Meruane, Matias Lasen, E. López Droguett, A. Ortiz-Bernardin, “Modal strain energy-based debonding assessment of sandwich panels using a linear approximation with maximum entropy.” 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

Entropy Vol. 19, No. 11, pp. 619, 2017 V. Meruane, M. 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
