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 ...
Calculation of the critical energy release rate Gc of the cement line in cortical bone combining experimental tests and finite element models

Giner Maravilla, Eugenio; Belda, R.; Arango-Villegas, Camila; Vercher Martínez, Ana; Tarancón Caro, José Enrique; Fuenmayor Fernández, Francisco Javier (Elsevier, 2017)

[EN] In this work, a procedure is proposed to estimate the critical energy release rate Gc of the so-called cement line in cortical bone tissue. Due to the difficulty of direct experimental estimations, relevant elastic ...
Estimation of the reinforcement factor xi for calculating the transverse stiffness E2 with the Halpin-Tsai equations using the finite element method

Giner Maravilla, Eugenio; Vercher Martínez, Ana; Marco, Miguel; Arango Villegas, Camila (Elsevier, 2015-06)

In this work, an estimation of the reinforcement factor n of the Halpin Tsai equations used to calculate the transverse stiffness E2 is provided. An improved estimation of the value xi=2 originally proposed by Halpin and ...
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 ...
Influence of the mineral staggering on the elastic properties of the mineralized collagen fibril in lamellar bone

Vercher Martínez, Ana; Giner Maravilla, Eugenio; Arango Villegas, Camila; Fuenmayor Fernández, Francisco Javier (Elsevier, 2015-02)

In this work, a three-dimensional finite element model of the staggered distribution of the mineral within the mineralized collagen fibril has been developed to characterize the lamellar bone elastic behavior at the sub-micro ...
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 ...
