Elastoplastic Model for Cemented Soils
Journal of Geotechnical and Geoenvironmental Engineering, 2001This paper presents a model for bonded or cemented soils within the framework of hardening plasticity. The model is based on the concepts that (1) the strength of a cemented soil can be considered to be made up of two components, the usual strength of the soil skeleton and the strength of cementation bonds; and (2) the deformation of the soil is ...

Eigenvalues of the Elastoplastic Constitutive Operator
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1994The authors studied the eigenvalues of the elastoplastic constitutive operator. Although the elastoplastic operator has been studied extensively, little information seems to be known about its eigenvalues. In this paper a formal solution to the eigenvalue problem of the elastoplastic constitutive operator is presented.

Elastoplastic Waves in Granular Materials
Journal of Applied Mechanics and Technical Physics, 2003For a description of the deformation of materials with different resistances to tension and compression, the conventional rheological diagram is supplemented by a new element --- rigid contact. It is used to construct a model of an ideal granular material possessing elastic and plastic properties.

Rubbers are polymers whose glass transition temperatures lie below the application temperature. Soft rubbers are lightly chemically cross-linked and hard rubbers are strongly chemically cross-linked. Elastoplasts are polymers which are physically cross-linked at the application temperature, but they can be worked like thermoplasts at higher ...

STRUCTURAL MECHANICS AND ANALYSIS OF CONSTRUCTIONS
Within the framework of the planar cross-section hypothesis, the construction of calculation formulas for determining stresses and deformations in cross- sections of an elastoplastic member under conditions of planar transverse bending is considered. The rod material works according to a bilinear tensile pattern and resists both tension and compression

Elastoplastic torsion: twist and stress
Computing in Science & Engineering, 2004Consider a long rod made of metal, plastic, rubber, or some other homogeneous material. Hold the rod at the ends and twist one end clockwise and the other end counterclockwise. This torsion (twisting) causes stresses in the rod. If the force we apply is small enough, the rod behaves as an elastic body: when we release it, it will return to its original

On Stability for Elastoplasticity of Integral-Type
2008The paper deals with a thermodynamically consistent formulation for nonlocal elastoplastic models. On the basis of recent observations, the proposed formulation introduces two internal variable fields related to plastic softening. The stability of the nonlocal model is proved.
