Inter-relationships among elastic constants for symmetrical or unsymmetrical laminates with cracked 90-plies
(Taylor & Francis, 2020-02-22)
The relations between the stiffness components of a symmetrical or unsymmetrical laminate having trans-verse matrix cracks only in the 90-degree laminas are explored in this work. The crack closure condition for these ...
Inter-relationships among stiffness matrix components for general laminates with transverse cracks in oblique plies
(Springer, 2019-02-28)
In this paper, nine inter-relationships linking the stiffness matrix components of symmetrical or unsymmetrical laminates having transverse matrix cracks in some of the off-axis plies is presented. The crack closure condition ...

Fatigue crack growth of a metastable austenitic stainless steel
(Elsevier, 2015-07)
The fatigue crack growth behavior of an austenitic metastable stainless steel AISI 301LN in the Paris region is investigated in this work. The fatigue crack growth rate curves are evaluated in terms of different parameters ...

Modeling the closure behavior of natural fractures in porous media using high aspect ratio interface elements
(2021-01-01)
Many reservoirs consist of fully saturated rock masses containing a very complex natural fracture network. In such cases a decrease in the fracture fluid pressure reduces its aperture due to an increase in the effective ...
One-pot thermo-remendable shape memory polyurethanes
(American Chemical Society, 2014-03-14)
Furan-based thermoset polyurethanes have been prepared in a one-pot fashion with the ability to self-mend under mild temperature conditions, by making use of a Diels-Alder shape-memory assisted self-mending (DASMASH) ...
Aplicação combinada de fraturamento hidraúlico e acidificação para estimulação de depósitos de gás não convencionais da Bacia do São Francisco
(Universidade Federal de Minas GeraisBrasilENG - DEPARTAMENTO DE ENGENHARIA MINASPrograma de Pós-Graduação em Engenharia Metalúrgica, Materiais e de MinasUFMG, 2022-08-25)
The production of oil and gas reservoirs is not something so simple as it appears.
Simply drilling a well through the reservoir is not a sufficient condition to put the well
into production. Most reservoirs need to be ...
