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

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…

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…

Impact location and quantification on an aluminum sandwich panel using principal component analysis and linear approximation with maximum entropy

Entropy 2017, 19(4), 137 V. Meruane, P. Véliz, E. López Droguett, A. Ortiz-Bernardin Abstract To avoid structural failures it is of critical importance to detect, locate and quantify impact damage as soon as it occurs. This can be achieved by impact identification methodologies, which continuously monitor the structure, detecting, locating, and quantifying impacts as they occur….

Consistent and stable meshfree Galerkin methods using the virtual element decomposition

International Journal for Numerical Methods in Engineering (2017) Accepted paper A. Ortiz-Bernardin, A. Russo, N. Sukumar Abstract Over the past two decades, meshfree methods have undergone significant development as a numerical tool to solve partial differential equations (PDEs). In contrast to finite elements, the basis functions in meshfree methods are smooth (nonpolynomial functions), and they…
