A simple procedure to evaluate Cauchy stress tensor at the macro level based on computational micromechanics under general finite strain states
(Elsevier Science, 2018-02)
This paper presents a new methodology to evaluate the Cauchy stress tensor at the macro level in computational micromechanics models. The use of control nodes to specify boundary conditions of a Representative Volume Element ...
Inverse finite element analysis using a simple reduced integration hexahedral solid-shell element
(Elsevier Science, 2020-10)
This paper introduces the inverse finite element method using simple brick elements that can be used for shell analysis. The proposed element is the inverse counterpart of an existing Lagrangean-based “direct” trilinear ...
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 ...
Finite Element Methods for Large-Strain Poroelasticity/Chemotaxis Models Simulating the Formation of Myocardial Oedema
(2022-07-22)
In this paper we propose a novel coupled poroelasticity-diffusion model for the formation of
extracellular oedema and infectious myocarditis valid in large deformations, manifested as an interaction between interstitial ...
Biomechanics Studies in Dentistry: Bioengineering Applied in Oral Implantology
(Lippincott Williams & Wilkins, 2009-07-01)
The application of engineering knowledge in dentistry has helped the understanding of biomechanics aspects related to osseointegrated implants. Several techniques have been used to evaluate the biomechanical load oil ...
Strain Injection Techniques in Numerical Modeling of Propagating Material Failure
(Cimne, 2012)
The methodology proposed in this research work explores the use of the straininjection concept in a combination of classical strain localization methods andembedded strong discontinuities, to remove the flaws (stress locking ...
