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…

Paper Submitted: Consistent and stable meshfree Galerkin methods using the virtual element decomposition

A. Ortiz-Bernardin, A. Russo, N. Sukumar, “Consistent and stable meshfree Galerkin methods using the virtual element decomposition,” submitted. 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 method are smooth (nonpolynomial functions),…
