Aspects of Mechanical Behavior and Modeling of a Tropical Unsaturated Soil
(2013-10-01)
The research studies the applicability of two elastoplastic models for the collapse prediction of the lateritic soil profile from Southeastern Brazil. These tropical soils have peculiar geotechnical behavior, due to their ...

Geometrical localization analysis of gradient-dependent parabolic Drucker -Prager elastoplasticity
(Pergamon-Elsevier Science Ltd, 2006-12)
In this work the geometrical method for the analysis of the localization properties of the thermodynamically consistent gradient--dependent parabolic Drucker-Prager elastoplastic model is presented. From the analytical ...
Elasto-plastic optimal profile of the flanges of a double-T steel beam
(ELSEVIER SCI LTD, 2008)
For a given amount of steel we look for the optimal profile of the width of the symmetrical flanges of a double-T steel beam, in order to optimize a weighted compromise between elastic performance, measured by the compliance, ...
A modified implicit-explicit integration scheme: an application to elastoplasticity problems
(Springer, 2016-01-01)
In this paper, a novel modified version of the implicit-explicit integration scheme (IMPL-EX) proposed by Oliver (Comput Methods Appl Mech Eng 197:1865-1889, 2008) is presented. This modified approach has as its main ...
Deformation and flow of amorphous solids: Insights from elastoplastic models
(American Physical Society, 2018-12)
The deformation and flow of disordered solids, such as metallic glasses and concentrated emulsions, involves swift localized rearrangements of particles that induce a long-range deformation field. To describe these ...
