Muchas veces la mejor manera de entender el significado de una palabra, es leer textos donde aparece dicha palabra. Por ese motivo te ofrecemos innumerables ejemplos extraidos de textos españoles seleccionados.
La agrupación viaja a Las Vegas para la realización del video de Ayer, el primer corte promocional del disco, dicho video fue realizado por Elastic People y dirigido por Carlos Pérez.
Griffith found an expression for the constant in terms of the surface energy of the crack by solving the elasticity problem of a finite crack in an elastic plate.
The crack relaxes the stress and hence reduces the elastic energy near the crack faces.
the stored elastic strain energy which is released as a crack grows.
Another significant achievement of Irwin and his colleagues was to find a method of calculating the amount of energy available for fracture in terms of the asymptotic stress and displacement fields around a crack front in a linear elastic solid.
In other words, a purely elastic solution may be used to calculate the amount of energy available for fracture.
The energy release rate for crack growth or strain energy release rate may then be calculated the change in elastic strain energy per unit area of crack growth, i.
where is the elastic energy of the system and is the crack length.
Irwin also showed that the strain energy release rate of a planar crack in a linear elastic body can be expressed in terms of the mode I, mode II, and mode III stress intensity factors for the most general loading conditions.
Today, it is the related quantity KIc which is called the fracture toughness and is now universally accepted as the defining material property in linear elastic fracture mechanics.
, ship-plate steel, are not perfectly elastic but undergo significant plastic deformation at the tip of a crack.
One basic assumption in Irwin's linear elastic fracture mechanics is that the size of the plastic zone is small compared to the crack length.
In such materials the assumptions of linear elastic fracture mechanics may not hold, that is,.
Normal Changes in the Elastic Configuration of the Human Pulmonary Trunk at Different Ages.
The Evolution of the Elastic Configuration of the Pulmonary Trunk in People Native to High Altitudes.
