Data-Driven Constitutive Modeling via Conjugate Pairs and Response Functions

open access: yesMathematics, 2022
Response functions completely define the constitutive equations for a hyperelastic material. A strain measure providing an orthogonal stress response, grants response functions directly from experimental curves.

Consideration of damping in a continuous medium using the rod approximation by A.R. Rzhanitsyn

open access: yesStructural Mechanics of Engineering Constructions and Buildings, 2023
The work is focused on creating a method for accounting of internal friction, which provides frequency independence, considers the dependence of internal friction on the level of the stress state, and is suitable for physically nonlinear tasks at large ...

Evaluation of isotropy in wet-mix sprayed concrete

open access: yesMateriales de Construccion, 2009
It is well known that there are differences between the fresh mix concrete and the placed concrete sprayed using dry or wet-mix process. Because of that, the characterization of such material is carried out in cores extracted parallel to the spray ...

Mechanical Characterization of Anhydrous Microporous Aluminophosphate Materials: Tridimensional Incompressibility, Ductility, Isotropy and Negative Linear Compressibility

open access: yesSolids, 2022
Here, a detailed mechanical characterization of five important anhydrous microporous aluminophosphate materials (VPI-5, ALPO-8, ALPO-5, ALPO-18, and ALPO-31) is performed using first principles methods based on periodic density functional theory.

Some geometrical properties of 4D homogeneous pseudo-Riemannian space with trivial isotropy [PDF]

open access: yesریاضی و جامعه, 2022
In this paper, we first consider $4D$ conformally flat homogeneous pseudo-Riemannian space with trivial isotropy, then, we investigate some geometrical properties such as being Ricci solitons and Walker on the spaces under consideration.
