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 ...
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 ...
On the compressive strength prediction for concrete masonry prisms
(SPRINGER, 2010)
The results of a combined experimental program and numerical modeling program to evaluate the behavior of ungrouted hollow concrete blocks prisms under uniaxial compression are addressed. In the numerical program, three ...
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 ...
Crystalline properties and morphological changes in plastically deformed isotatic polypropylene evaluated by X-ray diffraction and transmission electron microscopy
(Pergamon-elsevier Science LtdOxfordInglaterra, 2005)
Study of an anisotropic polymeric cellular material under compression loading
(ABM, ABC, ABPol, 2012)
This paper emphasizes the influence of micro mechanisms of failure of a cellular material on its phenomenological response. Most of the applications of cellular materials comprise a compression loading. Thus, the study ...
High-Strength Concrete Masonry Walls under Concentric and Eccentric Loadings
(Asce-amer Soc Civil Engineers, 2018-06-01)
Masonry walls and columns are common structural members that typically resist compressive loads, with a number of such members being required to resist combined axial load and out-of-plane bending due to direct out-of-plane ...
Growth and collapse of nanovoids in tantalum monocrystals
(Elsevier, 2010-12-02)
The growth and collapse of nanoscale voids are investigated for tantalum (a model body-centered cubic metal) under different stress states and strain rates by molecular dynamics (MD). Three principal mechanisms of deformation ...
Defect production in Ar irradiated graphene membranes under different initial applied strains
(Elsevier Science, 2017-02)
Irradiation with low energy Ar ions of graphene membranes gives rise to changes in the mechanical properties of this material. These changes have been associated to the production of defects, mostly isolated vacancies. ...
