For joining these dissimilar materials, adhesive bonding appears as an optimal solution, since mechanical fastening adds weight to the structure, and welding technology is not easily applicable to reinforced plastics and composites. However, one of the major drawbacks associated with bonded joints is the presence of stress concentrations at the overlap ends, especially in single lap joints. In order to reduce these stress concentrations, several techniques have been developed. One of these is the functionally graded adhesive, in which the adhesive properties gradually vary along the overlap length, leading to a more uniform stresses distribution and improving the joint strength. However, the manufacture of an adhesive layer with properties which gradually vary is complex in practice and so is the creation of numerical models that represent these configurations. In the present work, a numerical model for different-graded distribution of adhesive properties along the overlap was developed, using programmed step functions on finite element analysis background in order to discretize and simplify the continuous properties distribution gradient. Cohesive zone modelling was introduced in the numerical model, enabling it to effectively predict graded joint strength. The model was validated with experimental results of functionally graded joints available in the literature. The numerical model developed presents itself as a powerful tool to predict joint strength for functionally graded joints, without imposing large computational demands. <\/jats:p>","DOI":"10.1177\/0954408920916112","type":"journal-article","created":{"date-parts":[[2020,4,3]],"date-time":"2020-04-03T02:34:31Z","timestamp":1585881271000},"page":"436-445","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Numerical modelling of multi-material graded joints under shear loading"],"prefix":"10.1177","volume":"234","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6135-3665","authenticated-orcid":false,"given":"Mateus Q","family":"dos Reis","sequence":"first","affiliation":[{"name":"Departamento de Engenharia Mec\u00e2nica e Gest\u00e3o Industrial, Faculdade de Engenharia, Universidade do Porto (FEUP), Porto, Portugal"}]},{"given":"Ricardo JC","family":"Carbas","sequence":"additional","affiliation":[{"name":"Departamento de Engenharia Mec\u00e2nica e Gest\u00e3o Industrial, Faculdade de Engenharia, Universidade do Porto (FEUP), Porto, Portugal"},{"name":"Instituto de Ci\u00eancia e Inova\u00e7\u00e3o em Engenharia Mec\u00e2nica e Engenharia Industrial (INEGI), Universidade do Porto, Porto, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2750-8184","authenticated-orcid":false,"given":"Eduardo AS","family":"Marques","sequence":"additional","affiliation":[{"name":"Instituto de Ci\u00eancia e Inova\u00e7\u00e3o em Engenharia Mec\u00e2nica e Engenharia Industrial (INEGI), Universidade do Porto, Porto, Portugal"}]},{"given":"Lucas FM","family":"da Silva","sequence":"additional","affiliation":[{"name":"Departamento de Engenharia Mec\u00e2nica e Gest\u00e3o Industrial, Faculdade de Engenharia, Universidade do Porto (FEUP), Porto, Portugal"}]}],"member":"179","published-online":{"date-parts":[[2020,4,2]]},"reference":[{"key":"bibr1-0954408920916112","doi-asserted-by":"publisher","DOI":"10.1243\/14644207JMDA219"},{"key":"bibr2-0954408920916112","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijadhadh.2016.10.010"},{"key":"bibr3-0954408920916112","doi-asserted-by":"publisher","DOI":"10.1243\/14644207JMDA283"},{"key":"bibr4-0954408920916112","doi-asserted-by":"publisher","DOI":"10.1016\/j.compscitech.2008.04.003"},{"key":"bibr5-0954408920916112","doi-asserted-by":"publisher","DOI":"10.1016\/j.compositesb.2018.06.009"},{"key":"bibr6-0954408920916112","doi-asserted-by":"publisher","DOI":"10.1080\/00218464.2019.1583562"},{"key":"bibr7-0954408920916112","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijadhadh.2017.02.004"},{"key":"bibr8-0954408920916112","first-page":"41","volume":"15","author":"Volkersen O","year":"1938","journal-title":"Luftfahrtforschung"},{"key":"bibr9-0954408920916112","doi-asserted-by":"crossref","first-page":"A17","DOI":"10.1115\/1.4009336","volume":"66","author":"Goland M","year":"1944","journal-title":"J Appl Mech"},{"key":"bibr10-0954408920916112","unstructured":"Hart-Smith LJ.
