Analysis of the elastoplastic response in the torsion test applied to a cylindrical sample
(2019)
This work presents an experimental and numerical analysis of the mechanical behavior of a fixed-end SAE 1045 steel cylindrical specimen during the torsion test. To this end, an iterative numerical-experimental methodology ...
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 ...
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 ...
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 ...
Elastoplastic Characterization of Zn-Cu-Ti Alloy Sheets: Experiments, Modeling, and Simulation
(2021)
In this work, the elastoplastic behavior of Zn20 alloy sheets is characterized via a methodology that encompasses experiments, modeling, and numerical simulations. The experimental campaign includes tensile, compression, ...
Combined effects of structure and partial saturation in natural soils
(Ios Press, 2014-10)
The mechanical behaviour of natural clays is significantly affected by their in situ or initial structure in the form of cementation or interparticle bonding. This behaviour can differ substantially from the behaviour of ...
