Application of a Simplified Anisotropic Constitutive Model for Soft Structured Clay on Embankment Failure
Shirmohammadi, Ali; Hajialilue-Bonab, Masoud; Dadrasajirlou, Davood (Peer reviewed; Journal article, 2021)The design and maintenance of embankments is still a challenge in practical geotechnical engineering because of some features of soft sensitive soil behavior that are not considered in conventional methods. These features ... -
Effektivspenningsbaserte stabilitetsanalyser gjennom modellering av geologisk historie
Falstad, Tobias; Sæther, Teodor Opland (Master thesis, 2024)NTNU er involvert i et samarbeidsprosjekt med Statens vegvesen, Bane NOR og Norges vassdragsog energidirektorat. Prosjektet kalles Sauna og har til hensikt å forbedre beregningsmetodikken for stabiliteten av naturlige ... -

Investigation of Development of the Earth Pressure Coefficient at Rest in Clay During Creep in the Framework of Hyper-Viscoplasticity
Grimstad, Gustav; Long, Michael; Dadrasajirlou, Davood; Ghoreishian Amiri, Seyed Ali (Peer reviewed; Journal article, 2021)The in situ earth pressure coefficient at rest (K0) for clay has been widely discussed in the literature. In engineering practice, the empirical relationships between K0, the overconsolidation ratio (OCR), and the normally ... -
Modelling creep in clay using the framework of hyper-viscoplasticity
Grimstad, Gustav; Dadrasajirlou, Davood; Ghoreishian Amiri, Seyed Ali (Peer reviewed; Journal article, 2020)This paper addresses the derivation of creep models using the framework of hyper-viscoplasticity. It demonstrates that the formulations widely used already can easily be obtained using the hyper-viscoplastic formalism. ... -
Modified cam clay bounding surface hyper-viscoplastic model
Dadrasajirlou, Davood; Grimstad, Gustav; Ghoreishian Amiri, Seyed Ali; Degago, Samson Abate; Houlsby, G. T. (Journal article; Peer reviewed, 2024)Clays exhibit complex mechanical behaviour with significant viscous, nonlinear, and hysteric characteristics, beyond the prediction capacity of the well-known modified cam clay (MCC) model. This paper extends the MCC model ... -
On the isotache viscous modelling of clay behaviour using the hyperplasticity approach
Dadrasajirlou, Davood; Grimstad, Gustav; Ghoreishian Amiri, Seyed Ali (Journal article; Peer reviewed, 2022)The thermodynamically based hyperplasticity framework is employed to develop a hyper-viscoplastic constitutive model describing clay's creep and rate-dependent behaviour. The proposed model complies with the concept of the ... -
A set of hyper-viscoplastic critical state models with different friction mobilisation criteria
Dadrasajirlou, Davood; Grimstad, Gustav; Ghoreishian Amiri, Seyed Ali; Nordal, Steinar (Peer reviewed; Journal article, 2023)The approach of thermodynamics with internal variables, known as hyperplasticity, is used to develop a set of hyper-viscoplastic clay models that comply with the critical state soil mechanics and isotache viscosity. Different ...
