Influence of Pearlite Formation on the Ductility Response of Commercial Hadfield Steel
(Springer New York LLC, 2016-12)
This manuscript presents the singular event of pearlite occurrence in commercially produced Hadfield steel. A detailed characterization of the microstructure is performed and its influence on the mechanical properties of ...
Behaviour of steel-fibre-reinforced normal-strength concrete slender columns under cyclic loading
(2012-03-28)
The inclusion of ductility requirements is necessary to guarantee a safety design of concrete structures subjected to unexpected and/or reversal loads. It is important to outline that plastic hinges may develop in columns ...
A finite strain, finite band method for modeling ductile fracture
(Elsevier, 2012-02)
We present a finite deformation generalization of the finite thickness embedded discontinuity formulation presented in our previous paper [A.E. Huespe, A. Needleman, J. Oliver, P.J. Sánchez, A finite thickness band method ...
Embrittlement of electrical steel laminations by nitrogen pick-up during heat treatment
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
Heat treated electrical steel laminations have shown evidence of low ductility behavior, characterized by a small number of bends till fracture, on repeated bending tests. The laminations were produced using a new grade ...
A finite thickness band method for ductile fracture analysis
(Elsevier, 2009-12)
We present a finite element method with a finite thickness embedded weak discontinuity to analyze ductile fracture problems. The formulation is restricted to small geometry changes. The material response is characterized ...
Ductile fracture of advanced pipeline steels: Study of stress states and energies in dynamic impact specimens - CVN and DWTT
(2018)
© 2018 The Authors.The development of robust protocols for assessing the structural integrity of gas pipelines is of paramount relevance, since failures can lead to financial and human losses. In this scenario, the material's ...
Mathematical modeling of the behavior of earthquake resistant rods subjected to quenching treatments using the finite element methodModelación matemática del comportamiento de varillas sismorresistentes sometidas a tratamientos de temple mediante el método de elementos finitos
(Ciencia Digital Editorial, 2023)
Correlação da fenomenologia da fratura dúctil de gasodutos e corpos de prova dinâmicos de Charpy e DWTT empregando o modelo GTN a aços avançados classe API
(Centro Universitário FEI, São Bernardo do Campo, 2017)
O desenvolvimento de protocolos robustos para avaliação da integridade estrutural de dutos para transporte de gás é de extrema importância, já que uma falha pode levar não só a elevado prejuízo financeiro, mas também a ...
