Paper Accepted: Volume-Averaged Nodal Projection Method for Nearly-Incompressible Elasticity Using Meshfree and Bubble Basis Functions
Paper Accepted for Publication in Computer Methods in Applied Mechanics and Engineering A. Ortiz-Bernardin, J.S. Hale and C. J. Cyron, “Volume-averaged nodal projection method for nearly-incompressible elasticity using meshfree and bubble basis functions.” ABSTRACT We present a displacement-based Galerkin meshfree method for the analysis of nearly-incompressible linear elastic solids, where low-order simplicial tessellations (i.e., 3-node triangular…

Paper Accepted: A Finite Element Formulation for Stressed Bodies With Continuous Distribution of Edge Dislocations
Paper Accepted for Publication in Acta Mechanica A. Ortiz-Bernardin, D. Sfyris, ”A finite element formulation for stressed bodies with continuous distribution of edge dislocations.” ABSTRACT On using Noll’s theory of materially uniform but inhomogeneous bodies, a nonlinear finite element method for treating a body with a continuous distribution of edge dislocations is presented. To this end,…

Paper Accepted: Structural Damage Assessment Using Linear Approximation with Maximum Entropy and Transmissibility Data
Paper Accepted for Publication in Mechanical Systems and Signal Processing V. Meruane, A. Ortiz-Bernardin, “Structural damage assessment using linear approximation with maximum entropy and transmissibility data.” ABSTRACT Supervised learning algorithms have been proposed as a suitable alternative to model updating methods in structural damage assessment, being Artificial Neural Networks the most frequently used. Notwithstanding, the…
