Professor  Igor A. GUZ  Sixth Century Chair in Solid Mechanics Head of School of Engineering University of Aberdeen Fraser Noble Building, Aberdeen AB24 3UE, Scotland e-mail: i.guz@abdn.ac.uk http://www.abdn.ac.uk/engineering/people/profiles/i.guz The presence of cracks and delaminations considerably decreases the strength and the lifetime of engineering structures as well as significantly increases the cost of exploitation. In particular,

International Journal of Solids and Structures Vol. 51, No. 3-4, pp. 875-885, 2014 A. Ortiz-Bernardin, R. Bustamante, K.R. Rajagopal Abstract Recently, a very general and novel class of implicit bodies has been developed to describe the elastic response of solids. It contains as a special subclass the classical Cauchy and Green elastic bodies. Within the

Computer Methods in Applied Mechanics and Engineering Vol. 119, No. 25-28, pp. 1859-1871, 2010 A. Ortiz , M.A. Puso, N. Sukumar Abstract Numerical integration errors and volumetric locking in the near-incompressible limit are two outstanding issues in Galerkin-based meshfree computations. In this paper, we present a modified Gaussian integration scheme on background cells for meshfree

V. Meruane, A. Ortiz-Bernardin, “Damage identification using linear approximation with maximum-entropy and transmissibility data,” submitted. ABSTRACT Supervised learning algorithms have been proposed as a suitable alternative to model updating methods in damage assessment, being Artificial Neural Networks the most frequently used. Notwithstanding, the slow learning speed and the large number of parameters that need to
