A ductile damage criterion at various stress triaxialities
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
The paper discusses the effect of stress triaxiality on the onset and evolution of damage in ductile metals. A series of tests including shear tests and experiments oil smooth and pre-notched tension specimens wits carried ...
Experimental and numerical characterization of damage evolution in steels
(PERGAMON-ELSEVIER SCIENCE LTD, 2007)
This paper presents an experimental and numerical characterization of ductile damage evolution in steels subjected to large plastic deformations. To this end, a set of tensile tests combining load-unload tensile cycles is ...
An Anisotropic Model of Damage and Unilateral Effect for Brittle Materials
(World Acad Sci, Eng & Tech-waset, 2007-01-01)
This work deals with the initial applications and formulation of an aniscitropic plastic-damage constitutive model proposed for non-linear analysis of reinforced concrete structures submitted to a loading with change of ...
A new damage model for composite laminates
(ELSEVIER SCI LTDOXFORD, 2013-08-02)
Aircraft composite structures must have high stiffness and strength with low weight, which can guarantee the increase of the pay-load for airplanes without losing airworthiness. However, the mechanical behavior of composite ...
The evolution of civil responsability in contemporary constitutional law: from the moral damage in nature to moral damage in re ipsa
(Univ Santiago Compostela, 2017-01-01)
Moral damage is a king of indemnity that protects imaterial rights against injuries committed, those rights are inserted within personalities scope, previously deprived of judicial protection, once these rights were used ...
A multiaxial fatigue damage model for isotropic materials
(2020-01-01)
This paper presents a novel damage mechanics based failure model enabling the prediction of low cycle fatigue life and residual strength of isotropic structures under multiaxial loading. The approach herein proposed does ...
An Anisotropic Model of Damage and Unilateral Effect for Brittle Materials
(World Acad Sci, Eng & Tech-waset, 2014)
Static response of asymmetrically damaged metallic strands: Experimental and numerical approach
(Elsevier Ltd, 2018)
In this study, the effect of the presence of broken wires (damage) asymmetrically distributed on metallic strands surfaces on their static response is assessed. To this end, a general mechanical model for multilayered ...
Determination of the numerical parameters of a continuous damage model for the structural analysis of clay brick masonry
(Universidade Federal de São Carlos (UFSCar), Dept Engenharia Materials, 2012-12-01)
Models based on the continuous damage theory present good responses in representing the nonlinear behavior of reinforced concrete structures with loss of strength and stiffness of the material. However, damage theory is ...
