However, many materials can fail after a finite stochastic time under a constant subcritical strain, known as delayed fracture. In this work, we study this phenomenon by performing numerical simulations of a one-dimensional fiber bundle model under constant strain, with the aim of developing a model capable of reproducing delayed fracture. We observe that, within a limited strain range, delayed fracture can occur in this type of model if we introduce a continuous damage rule and a local stiffness redistribution.8 p.application/pdfengcc-by-nc-nd (c) Merin, 2026http://creativecommons.org/licenses/by-nc-nd/4.0/ElasticitatMecànica de fracturaTreballs de fi de grauElasticityFracture mechanicsBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
