ABSTRACT

GLARE, an acronym for "GLAss REinforced aluminium", is a fiber-metal laminate (FML) composite material.

GLARE consists of layers of aluminum and a glass fiber composite prepregged with epoxy resin. The glass fiber layers are oriented in different directions to improve the mechanical properties of the material.

Fiber-metal composite (FML) technology combines the advantages of metallic materials (strength and repair) with the advantages of fiber-reinforced polymers (high mechanical strength and stiffness, good fatigue and corrosion resistance). MLFs are being increasingly used in aeronautical and aerospace applications.

The objective of this CIMNE coffee talk is to evaluate by means of the well-known Finite Element Method (FEM) the efficiency of different models of constitutive equations for the materials that form the GLARE composite implemented in Kratos-Multiphysics.

SPEAKER CV

Alejandro Cornejo Velázquez is a Civil Engineer by the the Universitat Politècnica de Catalunya since 2015. Additionally, he holds a Master in Ingeniería de Caminos, Canales y Puertos and a PhD in Structural Analysis by the same university since 2017 and 2020, respectively.

Alejandro is currently a postdoctoral researcher at CIMNE aiming his scientific efforts in the improvement of the coupled FEM-DEM methodology for Fluid-Structure interaction, computational contact mechanics applied to industrial conforming processes and constitutive modelling of solids and composite materials (damage, plasticity, hyper-elasticity, viscoelasticity, fatigue, anisotropy, etc...) within the framework of Kratos-Multiphysics.
