... will be investigated in the future. Originality/value (1) A linear hydrate-soil constitutive model based on the Mohr–Coulomb yield criterion is proposed, which defines the internal friction angle, the elastic modulus and the cohesion as a linear function of hydrate saturation. (2) A fully coupled multi-physics...

...Jiří Halamka; Michal Bartošák Purpose The constitutive models determine the mechanical response to the defined loading based on model parameters. In this paper, the inverse problem is researched, i.e. the identification of the model parameters based on the loading and responses of the material...

... intends to develop a reasonable and practical constitutive model for rockfill materials to overcome the above problems. Design/methodology/approach The effects of anisotropy and grain crushing are comprehensively considered by the spatial position of the reference state line. After the improved...

...Florian Hüter; Frank Rieg Purpose A general first-invariant constitutive model has been derived in literature for incompressible, isotropic hyperelastic materials, known as Marlow model, which reproduces test data exactly without the need of curve-fitting procedures. This paper aims to describe...

.../approach In the proposed method, a simple critical-state based constitutive model is first adopted and implemented into a finite element code using the coupled Eulerian–Lagrangian technique for large deformation analysis. Simulations of column collapse with various aspect ratios are then conducted...

..., and rubber matrix damage. Design/methodology/approach The constitutive modeling is based on the continuum damage mechanics (CDMs) and the thermodynamics of irreversible process. The damage in rubber is described by an istropic law, whereas elasto-plastic continuum model has been proposed for cord–rubber...

...-static three steps. The soil behavior is described by a new rotational kinematic hardening elasto-plastic cyclic mobility constitutive model, while the footing and foundation are modeled as elastic rigid elements. Findings – The shallow (short-pile type) foundation has a better capacity...

... in structural engineering. As the reliability of numerical analysis largely depends on the validity of the constitutive models, the development of a concrete model suitable for natural fire analysis is addressed in the study. Design/methodology/approach The paper proposes theoretical considerations...
