To date, no constitutive model for wood under cyclic load exists which is able to incorporate its most important failure modes while considering plastic deformations and cyclic stiffness and strength degradation simultaneously. This paper presents the formulation and implementation of a plasticity-damage model with these characteristics within a continuum mechanics approach. The theoretical framework of both plasticity and damage models is described, and a detailed derivation of the constitutive equations required for their computational implementation and coupling as well as the return mapping and iterative algorithms for their integration are presented. The damage evolution process is handled by two independent scalar variables for tension and compression. A general orthotropic plasticity yield surface with isotropic hardening is employed to incorporate timber plastic flow in compression. A closed-form expression for the plasticity-damage consistent tangent operator is derived. It is demonstrated that the proposed constitutive model captures all the key characteristics required for an accurate modelling of timber under large deformation levels until failure.Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - ConcytecengElsevier LtdComputers & Structuresinfo:eu-repo/semantics/openAccessTimberPlasticity-1Continuum damage mechanics-1Orthotropy-1Cyclic loading-1Numerical algorithm-1https://purl.org/pe-repo/ocde/ford#2.05.01-1A three-dimensional plasticity-damage constitutive model for timber under cyclic loadsinfo:eu-repo/semantics/articlereponame:CONCYTEC-Institucionalinstname:Consejo Nacional de Ciencia Tecnología e Innovacióninstacron:CONCYTEC#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#20.500.12390/951oai:repositorio.concytec.gob.pe:20.500.12390/9512024-05-30 15:23:17.494http://purl.org/coar/access_right/c_14cbinfo:eu-repo/semantics/closedAccessmetadata only accesshttps://repositorio.concytec.gob.peRepositorio Institucional CONCYTECrepositorio@concytec.gob.pe#PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE##PLACEHOLDER_PARENT_METADATA_VALUE#<Publication xmlns="https://www.openaire.eu/cerif-profile/1.1/" id="8098f44f-9ef1-41f0-95aa-f16ee8b04121"> <Type xmlns="https://www.openaire.eu/cerif-profile/vocab/COAR_Publication_Types">http://purl.org/coar/resource_type/c_1843</Type> <Language>eng</Language> <Title>A three-dimensional plasticity-damage constitutive model for timber under cyclic loads</Title> <PublishedIn> <Publication> <Title>Computers &amp; Structures</Title> </Publication> </PublishedIn> <PublicationDate>2018</PublicationDate> <DOI>https://doi.org/10.1016/j.compstruc.2017.09.010</DOI> <ISI-Number>466621200048</ISI-Number> <Authors> <Author> <DisplayName>Sirumbal-Zapata, LF</DisplayName> <Person id="rp02598" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Malaga-Chuquitaype, C</DisplayName> <Person id="rp02597" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> <Author> <DisplayName>Elghazouli, AY</DisplayName> <Person id="rp02596" /> <Affiliation> <OrgUnit> </OrgUnit> </Affiliation> </Author> </Authors> <Editors> </Editors> <Publishers> <Publisher> <DisplayName>Elsevier Ltd</DisplayName> <OrgUnit /> </Publisher> </Publishers> <Keyword>Timber</Keyword> <Keyword>Plasticity</Keyword> <Keyword>Continuum damage mechanics</Keyword> <Keyword>Orthotropy</Keyword> <Keyword>Cyclic loading</Keyword> <Keyword>Numerical algorithm</Keyword> <Abstract>The performance of timber structures is governed by the nonlinear response at their connections, where high deformation levels and stress concentrations are developed, particularly when subjected to load reversals.
