Some remarks on the damage unilateral effect modelling for microcracked materials [PDF]
This study deals with the macroscopic modelling of the mechanical behaviour of microcracked materials and particularly with the unilateral aspect of such damage which leads, at the closure of microcracks, to a partial damage deactivation.

Extended granular micromechanics approach: a micromorphic theory of degree n [PDF]
For many problems in science and engineering, it is necessary to describe the collective behavior of a very large number of grains. Complexity inherent in granular materials, whether due the variability of grain interactions or grain-scale morphological factors, requires modeling approaches that are both representative and tractable.

ABSTRACT Geometrically nonlinear static analysis of materially imperfect composite doubly curved shells is investigated via the generalised differential quadrature method. The effects of both shear and thickness deformation are considered through a thickness‐ and shear‐deformable third‐order theory formulated in curvilinear coordinates, while the ...

Generalized Finite-volume Micromechanics Theory for Heterogeneous Materials [PDF]
In the last decades, new generations of advanced materials have been designed and manufactured for specific applications. Micromechanics of heterogeneous materials plays an important role in the development of these materials, enabling efficient analyses of composite materials with complex geometries, circumventing the traditional trial-and-error ...

ABSTRACT Localized deformation in dense granular materials, often culminating in the formation of shear bands, is a key failure mechanism in geotechnical and material systems. However, predicting the onset of such localization remains a fundamental challenge due to the system's inherent inelasticity and microstructural complexity.

Variational approach for the quantum Zakharov system [PDF]
The quantum Zakharov system is described in terms of a Lagrangian formalism. A time-dependent Gaussian trial function approach for the envelope electric field and the low-frequency part of the density fluctuation leads to a coupled, nonlinear system of ...
