Application of a generalized continuous Mohr–Coulomb criterion
Grimstad, Gustav; Rønningen, Jon Abusland; Nordal, Steinar (Chapter, 2018)This paper presents an application of a generalized failure criterion for soils. The presented formulation was originally adopted by the authors to round the corners of the Mohr–Coulomb (MC) yield surface in principals ... -
Effective Stress based Model for Natural Soft Clays incorporating Restructuration
Bjerre, Jesper; Rønningen, Jon Abusland; Grimstad, Gustav; Nordal, Steinar (Chapter, 2018)Several advanced constitutive models have been developed over the last decades to reproduce the mechanical response of natural soft clays observed during laboratory testing and in the field. Features such as anisotropy, ... -
On the convexity of yield and potential surfaces in rotational hardening critical state models
Rønningen, Jon Abusland; Grimstad, Gustav; Nordal, Steinar (Chapter, 2018)This article shows that a common formulation often used for an anisotropic modified cam clay yield and potential surface with a modified Lode angle dependency may become concave for high values of anisotropy. Concave ...
