Raul Duarte Salgueiral Gomes Campilho; Marcelo Francisco de Sousa Ferreira de Moura; Ana Maria Jacinto Pina Barreto; José J. L. MoraisAn experimental and numerical study is presented concerning the fracture behaviour of scaled specimens of wood beams repaired with a carbon–epoxy patch under four-point bending.In this work,a numerical technique is proposed to simulate the fracture behaviour of these repairs,which includes the possibility of cohesive failure in the adhesive layer,failure with in the wood beam in different planes,and inter...
Modelling the tensile fracture behaviour of CFRP scarf repairs
Raul Duarte Salgueiral Gomes Campilho; Marcelo Francisco de Sousa Ferreira de Moura; Arnaldo Manuel Guedes Pinto; José J. L. Morais; J. Sabino DominguesAn experimental and numerical study concerning the tensile behaviour of adhesively-bonded carbon-epoxy scarf repairs is presented, using scarf angles ranging from 2° to 45°. A mixed-mode cohesive damage model adequate for ductile adhesives was used to simulate the adhesive layer. The cohesive laws of the adhesive layer, composite interlaminar and composite intralaminar (in the transverse and fibre directions) i...
