TL;DR: In this article, the authors studied the mechanical anisotropic properties of aluminum alloy using multi-level approaches for strain-rate and temperature-sensitive large plastic deformation of polycrystalline aggregates.
59 citations
TL;DR: In this article, the authors study the convergence of both responses in antiplane elasticity of sheets with non-periodic, random distributions of thin needle-shaped inclusions and show that, with the needles' stiffness decreasing and their slenderness growing, the RVE tends to be very large.

TL;DR: In this paper, a finite element model for predicting the mechanical behavior of polypropylene (PP) composites reinforced with carbon nanotubes (CNTs) at large deformation scale is presented.

TL;DR: In this article, the influence of sample geometry on wave type was evaluated on solid isotropic aluminum samples and it was shown that the extensional wave propagation mode requires transmission of truly slender samples (required slenderness ratio of 20 or larger for wavelengths equal to the wave travel distance).

TL;DR: In this article, the macroscopic stress states on the yield surface can be obtained from the solution to non-linear viscous problems defined on a representative volume element, and the role of the interface between the matrix and the inclusions is investigated.
Abstract: At the microscopic scale, concrete can be considered as a frictional matrix (cement paste) surrounding rigid inclusions (aggregate or sand inclusions) The present paper proposes a theoretical approach to the strength criterion of such a composite material It is shown that the macroscopic stress states on the yield surface can be obtained from the solution to non-linear viscous problems defined on a representative volume element The practical determination of the yield surface implements a non-linear homogenization scheme based on the modified secant method The role of the interface between the matrix and the inclusions is also investigated Two extreme modellings are considered: perfect bonding and non-frictional interfaces In both cases, the method yields a macroscopic strength criterion of the Drucker-Prager type The macroscopic friction angle is a function of that of the matrix and of the volume fraction of the inclusions In the case of perfect bonding, the inclusions have a reinforcing effect In contrast, this may not be true for a non-frictional interface
