Modelo constitutivo MCC Hiperplástico com dano acoplado aplicado a solos estruturados

Abstract: RESUMO -Este trabalho apresenta um modelo constitutivo elasto-plástico com dano acoplado derivado a partir da definição de potenciais termodinâmicos aplicado à modelagem do comportamento tensão-deformaçãoresistência de solos estruturados. O modelo pertence à família dos modelos Cam-Clays Modificados e emprega variáveis internas de plasticidade e dano na sua formulação. O trabalho apresenta simulações de ensaios triaxiais e oedométricos em solos. A incorporação do efeito de dano permite a representação dos efei… Show more

“…Various advanced constitutive models have been employed and tested. Some researchers used enhanced versions of Cam Clay, introducing isotropic damage (Puppi et al, 2018), influence of structure (Mendoza et al, 2014) or the subloading surface (Mendoza and Muniz de Farias, 2020). Others (Azevedo et al, 2006) have used the Lade's model and the discrete element modeling approach (Ibañez, 2008).…”
