Common root causes in recent failures of cranes
(Elsevier, 2014-02)
Catastrophic failure of cranes is a potentially very dangerous event and has often fatal consequences. The failures of two cranes are discussed in this study. Both cranes have different designs, but common root causes have ...
Post-failure behaviour of impulsively loaded circular plates
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
The dynamic plastic response of a simply supported circular plate is analysed. Emphasis is given to the plate behaviour after it has broken free from the supports due to a local material failure. The theoretical rigid ...
Diffuse and localized failure predictions of Perzyna viscoplastic models for cohesive-frictional materials
(Planta Piloto de Ingeniería Química, 2002-12)
Viscoplastic constitutive formulations are characterized by instantaneous tangent operators which do no exhibit degradation from the elastic properties. As a consequence Viscoplastic materials descriptions were often ...
O EEG na insuficiencia renal cronica. II. Atividades paroxisticas
(1997-01-01)
The authors describe paroxismal epileptiform EEG abnormalities in patients with chronic renal failure. One patient presented paroxismal epileptiform abnormalities in the right parietal region which proceded partial ...

Numerical assessment of temperature effects on concrete failure behavior
(Springer, 2018-08)
This work focuses on the evaluation of temperature effects on concrete failure behavior and modes by means of a realistic thermodynamically consistent non-local poroplastic constitutive model, previously developed by the ...
Continuum approach to the numerical simulation of material failure in concrete
(Wiley, 2004-06)
Some new aspects of the continuum strong discontinuity approach (CSDA) to model material failure in geomaterials are addressed. A new global algorithm, for tracking multiple crack lines/surfaces in 2D/3D cases is proposed. ...
Strain Injection Techniques in Numerical Modeling of Propagating Material Failure
(Cimne, 2012)
The methodology proposed in this research work explores the use of the straininjection concept in a combination of classical strain localization methods andembedded strong discontinuities, to remove the flaws (stress locking ...
Strain localization, strong discontinuities and material fracture: Matches and mismatches
(Elsevier Science Sa, 2012-10)
The work focuses on the connections of strain localization modeling of material failure and discrete fracture mechanics. It is an attempt to give an answer to the old question of whether the finite element solutions of ...
