Evaluation of a coach door under a frontal impact

Rogério Lopes, Francisco Barros, Francisco Q. de Melo, Nuno V. Ramos, Rafael Cunha, Ricardo Maia, Rui Rodrigues, M.P.L. Parente, P.M.G. Moreira

The vehicle´s body front pillar should absorb most of the striker kinetic energy, while only a fraction of that is absorbed by the door structure. This study aims to discuss the…

Prediction of the failure strain of FRP sheets on confined concrete columns with circular cross-section

Paulo Silva Lobo, Mariana Jesus, Paulo S.A. Freitas

In this paper a model for the prediction of the failure strain of fiber reinforced polymer (FRP) sheets is proposed, based on a significant database consisting of results reported…

Evaluation of the influence of preliminary low-velocity impacts on the residual fatigue life of CFRP composites

Oleg Staroverov, Dmitriy Lobanov, Elena Strungar, Ekaterina Lunegova

The main purpose of this study was to evaluate the mechanical behaviour of layered fibrous carbon-fibre reinforced plastic (CFRP) under complex low-speed bending and impact loads…

On the use of finite differences for vibration-based damage localization in laminated composite plates

Tomás Oliveira, José V. Araújo dos Santos, Hernâni Lopes

Laminated composite materials are a staple of modern material development, with extremely strong fibers being combined with resins to form versatile and efficient engineering…

On the inverse identification of wood elastic properties using a DIC-based FEMU approach

João Henriques, José Xavier, António Andrade-Campos

This work aims to identify the linear elastic orthotropic material paramters of Pinus pinaster Ait. wood, using full-field measurements and an inverse identification strategy…

Quantitative thermography: a powerful but simple tool to assess the fatigue strength of metals in a one-specimen test–capabilities and limitations in the test setup

Jonas Rauber, Christian Motz, Florian Schaefer

The aim of the study is the question, that is, which evaluation method for the measured temperature profile is more suitable and feasible for quantitative thermometry (QT): A…

Detection and measurement of beam deflection in the Madeira Airport runway extension using digital image correlation

Francisco Barros, Susana Aguiar, Pedro J. Sousa, António Cachaço, Nuno V. Ramos, Paulo Tavares, P.M.G. Moreira, Luís Oliveira Santos, Min Xu, Elsa Franco

Part of the runway at Madeira Airport is a platform above the sea at a 60 m height, supported by a series of frames. When aircraft land on this section, a load is exerted on the…

Identification of corrosion formation in CORTEN steel using acousto-ultrasonic approach and deep learning

Claudia Barile, Caterina Casavola, Giovanni Pappalettera, Vimalathithan Paramsamy Kannan

The acousto-ultrasonic approach is used for propagating stress waves through different configurations of CORTEN steel specimens. The propagated waves are recorded and analysed by…
