A review on recent advances in numerical modelling of bone cutting

Marco, Miguel; Rodríguez Millán, Marcos; Santiuste, Carlos; Giner Maravilla, Eugenio; Henar Miguélez, María (Elsevier, 2015-04)

[EN] Common practice of surgical treatments in orthopaedics and traumatology involves cutting processes of bone. These operations introduce risk of thermo-mechanical damage, since the threshold of critical temperature ...
Aplicación de modelos de daño progresivo al comportamiento mecánico de una osteona mediante el método de los elementos finitos

Arango Villegas, Camila (Universitat Politècnica de València, 2014-07-31)

[EN] In this Master Thesis the compressive mechanical behavior of an osteon is modeled by the finite element method. The osteon is the basic estructural unit of the cortical bone tissue. In the model, the microstructure ...
Computer modelling of RF ablation in cortical osteoid osteoma: Assessment of the insulating effect of the reactive zone

Irastorza, Ramiro M.; Trujillo Guillen, Macarena; Martel Villagran, Jose; Berjano, Enrique (Taylor & Francis, 2016-02-10)

Purpose: The aim was to study by computer simulations the insulating role of the reactive zone surrounding a cortical osteoid osteoma (OO) in terms of electrical and thermal performance during radiofrequency ablation ...
Estimación de propiedades elásticas y resistentes de tejido óseo cortical a partir de ensayos experimentales y modelos de elementos finitos

Tudela Desantes, Carlos (Universitat Politècnica de València, 2017-01-10)

[EN] In this final master thesis, the results from 3-point bending tests on cortical tissue samples of small dimensions are presented, together with its correlation modeled by finite elements. Some of the most relevant ...
Homogenized stiffness matrices for mineralized collagen fibrils and lamellar bone using unit cell finite element models

Vercher Martínez, Ana; Giner Maravilla, Eugenio; Arango Villegas, Camila; Tarancón Caro, José Enrique; Fuenmayor Fernández, Francisco Javier (Springer Verlag (Germany), 2014-04)

Mineralized collagen fibrils have been usually analyzed like a two phase composite material where crystals are considered as platelets that constitute the reinforcement phase. Different models have been used to describe ...
Jaw tissues segmentation in dental 3D CT images using fuzzy-connectedness and morphological processing

Llorens Rodríguez, Roberto; Naranjo Ornedo, Valeriana; López-Mir, Fernando; Alcañiz Raya, Mariano Luis (Elsevier, 2012-11)

The success of oral surgery is subject to accurate advanced planning. In order to properly plan for dental surgery or a suitable implant placement, it is necessary an accurate segmentation of the jaw tissues: the teeth, ...
Modelo de una osteona de hueso cortical mediante elementos finitos incorporando elementos cohesivos

Atucha Alegría, Joseba (Universitat Politècnica de València, 2016-03-11)

[EN] In this Máster Thesis an osteon extracted from an electronic microscope image of a sheep tibia cortical bone is modelled using the finite element method. The model is composed by all the compact bone parts, such as ...
Numerical modelling of the mechanical behaviour of an osteon with microcracks

Giner Maravilla, Eugenio; Arango Villegas, Camila; Vercher Martínez, Ana; Fuenmayor Fernández, Francisco Javier (Elsevier, 2014-09)

In this work, we present two strategies for the numerical modelling of microcracks and damage within an osteon. A numerical model of a single osteon under compressive diametral load is developed, including lamellae organized ...
Study of the mechanical behavior of cortical bone microstructure by the finite element method

Arango Villegas, Camila (Universitat Politècnica de València, 2016-07-14)

[EN] Cortical bone tissue is the responsible of giving support and structure to vertebrates. For that reason, understanding and analyzing its behavior is needed from each different hierarchical level that composes it. The ...
The influence of anisotropy in numerical modelling of orthogonal cutting of cortical bone

Santiuste, C.; Rodríguez Millán, M.; Giner Maravilla, Eugenio; Miguélez, H. (Elsevier, 2014-09)

Cutting operations in bone are involved in surgical treatments in orthopaedics and traumatology. The importance of guaranteeing the absence of damage in the living workpiece is equivalent in this case to ensuring surface ...
