Partição de deformação em aços dual-phase
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2022-09-29)
The tailoring of new alloys often requires improvement in strength, for performance, and ductility to support mechanical processing until the final shape is achieved. Important advances have been obtained in the last decades ...
Direct inversion of the Longitudinal Ray Transform for 2D residual elastic strain fields
(2024)
We examine the problem of Bragg-edge elastic strain tomography from energy resolved neutron transmission imaging. A new approach is developed for two-dimensional plane-stress and plane-strain systems whereby elastic strain ...
A finite element analysis of some boundary value problems for a new type of constitutive relation for elastic bodies
(Springer, 2016)
Recently, there has been interest in the study of a new class of constitutive relation, wherein the
linearized strain tensor is assumed to be a function of the stresses. In this communication, some boundary
value problems ...
Local electromethanical properties of the CaCu 3Ti 4O 12 ceramics
(2010-12-01)
Scanning probe microscopy (SPM) was used to probe piezoelectric vibrations and local conductivity in CaCu 3Ti 4O 12 (CCTO) ceramics at room temperature. Piezoelectric contrast was observed on the polished surfaces of CCTO ...
A spectral approach for nonlinear transversely isotropic elastic bodies, for a new class of constitutive equation: Applications to rock mechanics
(Springer, 2020)
A constitutive equation is provided for nonlinear transversely isotropic elastic solids, wherein the linearized strain tensor is assumed to be a function of the Cauchy stress tensor; this elastic constitutive equation ...
Crystallographic Texture Evolution of a Zinc Sheet Subjected to Different Strain Paths
(Springer, 2017-03)
The use of zinc sheets has largely increased in the last years, fundamentally because of new tendencies in architecture and, at the same time, due to its excellent properties, as corrosion resistance under aggressive ...
Uniaxial near plane strain tensile tests applied to the determination of the FLC0 formabillity parameter.
(São Carlos, 2014)
An alternative procedure for the determination of the FLC0 value, the limit strain value corresponding to the plane strain mode of the Forming Limit Curves (FLC), a critical parameter in the sheet formability analysis, is ...
A "Prism" solid element for large strain shell analysis
(Elsevier, 2012-10)
In this paper a triangular prism solid element for the analysis of thin/thick shells undergoing large elastic–plastic strains is developed. The element is based on a total Lagrangian formulation and uses as strain measure ...
Raman spectroscopy as a reliable tool for strain analysis in iii-nitride superlattices
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2021-09-02)
Since its discovery, the Raman effect has been a great ally in the structural investigation of a wide variety of materials, from macro to nanoscale. However, despite the remarkable sensitivity of techniques based on Raman ...
