An implicit/explicit integration scheme to increase computability of non-linear material and contact/friction problems
(Elsevier Science Sa, 2008-12)
An implicit/explicit integration scheme for non-linear constitutive models is presented. It aims at providing additional computability to those solid mechanics problems were robustness is an important issue, i.e. material ...
Análise numérica da indentação de materiais elastoplásticos
(BrasilUFSMCentro de Tecnologia, 2022-08-03)
This work aims at performing a numerical analysis on the indentation of elastoplastic materials. The simulations are carried out using the commercial finite element code Abaqus, employing an axisymmetric model. An important ...
Estudo e desenvolvimento de código computacional para avaliação do comportamento elastoplástico de treliças planas via Métodos dos Elementos Finitos
(Universidade Tecnológica Federal do ParanáCampo Mourao, 2012-05-28)
In this work a finite element method formulation for elastoplastic analysis of two-dimensional trusses is presented. The integral statement necessary for formulation in terms of the finite element approximation was supplied ...
Geometry method for localization analysis in gradient-dependent J2 plasticity
(American Society of Mechanical Engineers, 2006-12)
In this work the geometrical method for the assessment of discontinuous bifurcation conditions is extended to encompass gradient-dependent plasticity. To this end, the gradient-dependent localization condition is cast in ...
Creep dynamics of athermal amorphous materials: A mesoscopic approach
(Royal Society of Chemistry, 2018-09)
Yield stress fluids display complex dynamics, in particular when driveninto the transient regime between the solid and the flowing state. Inspired by creep experiments on dense amorphous materials, we implement mesoscale ...
The truss‐like discrete element method in fracture and damage mechanics
(Emerald Group Publishing Limited, 2011-12)
Purpose: It is the purpose of this paper to further develop the truss-like discrete element method (DEM) in order to make it suitable to deal with damage and fracture problems. Design/methodology/approach: Finite and ...
Damage severity estimation of an elastoplastic single-degree-of-freedom oscillator from its ground and response acceleration
(Structural Control and Health Monitoring, 2014-01)
for the estimation of occurrence in time and severity of damage of a damped elastoplastic single-degree-of-freedom
oscillator from its absolute and ground accelerations, using ductility as the adopted damage index. This ...
Springback Prediction: Simplified Model
(Publisher: Association For Iron And Steel Technology, AISTECH, 2018)
Elasto-Plastic Behaviour of Soil Aggregates and the Soil Matrix as a Function of Physical Properties in three Soils of Central Chile
(Catena Verlag, 2013)
This study assessed the elasto-plastic behaviour of soil aggregates and of the soil
matrix in three soils of central Chile in terms of their structural development,
clay content and internal tension. Soil samples (cores ...
