  In this work the problem of overcoming local minima in the solution of nonlinear optimisation problems is addressed. As a first step, the existing nonlinear local and global optimisation methods are reviewed so as to ...
• Numerical homogenization and experimental validation of a composite plate using modal analysis 

  Pérez Martínez, Marco Antonio; Gil Espert, Lluís; Hammami, Farah; Neifar, Mondher; Chafra, Moez (2010)
  Text en actes de congrés
  Accés restringit per acord de confidencialitat

  A Finite Element (FE) simulation and an experimental (EXP) test are performed for the validation of the homogenized global elastic properties of a composite material plate. Composite material homogenization is based on ...
• A micromechanical approach to modeling the effect of impact induced damage on the vibration response of CFRP laminates 

  Pérez Martínez, Marco Antonio; Gil Espert, Lluís; Oller Martínez, Sergio Horacio; Felippa, Carlos (2015)
  Text en actes de congrés
  Accés restringit per política de l'editorial

  This work deals with modeling the effect of low-velocity impact damage upon the vibration response of CFRP laminates through a micro-mechanical description of the induced internal damage. The serial-parallel (SP) continuum ...

  Modelling unreinforced, TRM-strengthened and FRP-strengthened brick masonry walls subjected to eccentric compressive load 

  Bernat Masó, Ernest; Gil Espert, Lluís; Roca Fabregat, Pedro (2015)
  Text en actes de congrés
  Accés obert

  The mixed bending/buckling collapse mode of brick masonry walls might be prevented by installing strengthening systems which provide tensile strength. Among others, the Textile Reinforced Mortar (TRM) and Fibre Reinforced ...
• Evaluation of deflections for PFRP-RC hybrid beams with complete and partial shear connection 

  Neagoe, Catalin Andrei; Gil Espert, Lluís (2014)
  Text en actes de congrés
  Accés restringit per política de l'editorial

  The current paper presents various analytical models suitable for the evaluation of hybrid beam deflections, ranging from simple to complex expressions, which can be applied in common design practice. The formulations are ...
