Experimental characterization of short crack nucleation and growth during cycling in lean duplex stainless steels
(Elsevier, 2014-06)
Considering that many applications of Lean Duplex Stainless Steels (LDSSs) involve cyclic loading, the aim of this paper is to study short crack initiation and growth during low (LCF) and high cycle fatigue (HCF) in AL ...
Short fatigue crack propagation during low-cycle, high cycle andvery-high-cycle fatigue of duplex steel – An unified approach
(Elsevier, 2014-07)
The present paper reviews experimental results on the fatigue damage of austenitic–ferritic duplex steel under various load levels ranging from LCF to VHCF, placing the focus towards the relationship between the crystallographic ...
Microstrain measurements and damage analysis during tensile loading of intercritical austempered ductile iron
(Wiley Blackwell Publishing, Inc, 2020-08)
The study focuses on the measurement of microstrain and the assessment of damage during tensile loading of intercritical austempered ductile iron by using digital image correlation technique and in situ observations. The ...
An adaptive concurrent two-scale FE model to predicting crack propagation in concrete
(2018-01-01)
Finite element analysis including explicitly the details of the heterogeneities (finer-scale) can dramatically increase the numerical effort and memory demand. To minimize these drawbacks, a new concurrent adaptive multiscale ...

Quantificação da incerteza de modelo de Forman via metodologia "Fast Crack Bounds"
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2018-11-26)
The linear elastic fracture mechanics (LEFM) allows quantification of the relationship
between the material properties, the stress level, the presence of crack-generating
defects and crack propagation mechanisms. There ...
Análise por método de diferenças finitas da propagação dinâmica de trinca em uma haste em queda livre chocando-se transversalmente contra um apoio rígido

Evaluation of environmentally assisted fracture of austempered ductile iron (ADI) under cyclic load bearing
(Wiley, 2015-12-29)
This paper aims to characterize the behaviour of austempered ductile iron (ADI) under cyclic load bearing and its surface in contact with water.The first part is devoted to verifying the drop in Ultimate tensile strength ...
