Computing upper and lower bounds for the J-integral in two-dimensional linear elasticity
(2006-01)
Article
Accés obertWe present an a posteriori method for computing rigorous upper and lower bounds for the J-integral in two-dimensional linear elasticity. The J-integral, which is typically expressed as a contour integral, is recast as a ... -
Effects of build orientation and heat treatments on the tensile and fracture toughness properties of additively manufactured AlSi10Mg
(2021-10-05)
Article
Accés obertThe purpose of this study aimed to examine how build orientation and heat treatments affect microstructure, and consequently, the mechanical properties obtained from tensile and fracture toughness tests of additively ... -
Essential work of fracture, crack tip opening displacement, and J-integral relationship for a ductile polymer film
(2016-10)
Article
Accés obertA unique set of double-edge notched tension specimens of a Polyethylene Terephthalate Glycol-modi¿ed ¿lm was tested in mode I, plane stress. The load was registered on a universal testing machine. The displacements, ligament ... -
Identification of fracture toughness parameters to understand the fracture resistance of advanced high strength sheet steels
(2020-04-15)
Article
Accés obertThe fracture toughness of four advanced high strength steel (AHSS) thin sheets is evaluated through different characterization methodologies, with the aim of identifying the most relevant toughness parameters to describe ... -
Notch effect on the fracture of a polymeric film
(2018-06-01)
Article
Accés obertThe fracture behavior of a bio-based thermoplastic copolyester film has been studied by combining the essential work of fracture, the J-integral, and the crack tip opening displacement characterization methods on double ... -

Tesi
Accés obertPolymers have a wide range of applications. Their ability to be shaped into multiple forms makes it possible to obtain polymer films, which are highly used in industries such as food and pharmaceuticals. Characterization ... -
The fracture testing of ductile polymer films: Effect of the specimen notching
(Elsevier, 2017-10-01)
Article
Accés obertThe fracture of a ductile polymer film, a heterophase ethylene-propylene block copolymer, has been studied, combining a range of characterisation methods in an attempt to provide a better understanding of the intricate ... -
The post-yield fracture of a ductile polymer film: Notch quality, essential work of fracture, crack tip opening displacement, and J-integral
(2017)
Article
Accés obertDouble edge notched tension (DENT) specimens of a polyethylene terephthalate (PET) film were tested in an universal testing machine, measuring the displacements and the ligament lengths with a digital image correlation ...
