Propagation regimes, transition times, and approximate universality in 2D hydraulic fracture propagation with fluid lag
(Elsevier Science, 2021-09)
During its lifetime, a hydraulic fracture is known to traverse a trajectory in a region of a parametric space of non-dimensional evolutionary parameters. The topology of this diagram depends upon the phenomena considered. ...
Numerical life estimation after fatigue failure of a complex component
(Wiley Blackwell Publishing, Inc, 2005-06)
Failure of a large ethylene‐reciprocating compressor was found to be due to fatigue growth of cracks in the crosshead of one of the cylinders, initiated at material defects near stress raisers. Total fatigue crack growth ...
Análise experimental e numérica do processo de ressecamento e fissuramento de solos expansivos com inclusão de elementos rígidos
(Universidade Federal de PernambucoUFPEBrasilPrograma de Pos Graduacao em Engenharia Civil, 2020)
Stade I d'endommagement par fatigue plastique oligocyclique (FPO) dans un acier inoxydable duplex (AID)Stage I in low-cycle fatigue (LCF) damage in a duplex stainless steel (DSS)
(EDP Sciences, 2012-03-15)
The cyclic plastic activity and the initiation and propagation of the first microcracks in a forged austenitic-ferritic stainless steel under low-cycle fatigue at room temperature are studied from a priori EBSD measurements, ...
Quantificação da incerteza do modelo de proddle via metodologia fast crack bounds
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2017-12-05)
The study of a structural component is more realistic when it is admitted that the component already has cracks. The area that studies this phenomenon is the fracture mechanics. The component which is cracked and subjected ...
Quantificação da incerteza do modelo randômico de McEvily via metodologia fast crack bounds - Monte Carlo
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2019-12-18)
The fracture mechanics studies the behavior of cracks in order to understand and predict their propagation until the fracture, in order to avoid catastrophic accidents, since about 80% of failures in industries occur due ...
Estudo do efeito do processo de shot peening na taxa de propagação de trinca por fadiga na liga aeronáutica 2024 - T3
(Universidade Estadual Paulista (UNESP), 2015)
Hydrogen-induced cracking and corrosion behavior of friction stir welded plates of API 5L X70 pipeline steel
(2021-08-10)
The use of friction stir welding (FSW) has proven to be an excellent alternative to join engineering components. Although FSW has had a significant development in recent years, challenges for new applications have been ...
Caracterización de un recubrimiento de acero inoxidable martensitico sometido a ciclos térmicos
(Universidad Michoacana de San Nicolás de Hidalgo, 2009-02)
Tae Kwon Ha and Hwan-Jin Sung define thermal fatigue as a complex phenomenon that is present in materials exposed to cyclical changes of temperatures in the presence or absence of external loads. During thermal fatigue, ...
