Experimental Analysis of Fracture Processes in Concrete
(The Brazilian Society of Mechanical Sciences, 2001)
Coupled Thermo-Hydro-Mechanical Numerical Modeling of Evolving Fractures in Rocks
(Springer, 2021-04-22)
We present a numerical technique capable of handling evolving fractures in rocks triggered by coupled thermo-hydro-mechanical (THM) phenomena. The approach is formulated in the context of the finite-element method (FEM) ...
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 ...
A new discrete fracture approach based on the use of coupling finite elements for modeling fluid transport in naturally fractured porous media
(2021-12-01)
The presence of natural fractures in a porous medium strongly influences the fluid flow path. The complex geometric characteristics of the fracture network create preferential channels that change the permeability of the ...
The synergy effect of carbon/glass/epoxy hybrid laminate in Mode I delamination: A physical microfracture analysis
(2020-11-01)
The adoption of carbon/glass fiber hybrid composites is an economical alternative to high-cost carbon/epoxy composites and helps to address environmental issues. However, the addition of another type of fiber modifies the ...
From continuum mechanics to fracture mechanics: the strong discontinuity approach
(Pergamon-Elsevier Science Ltd., 2002-09)
The paper deals with the strong discontinuity approach and shows the links with the decohesive fracture mechanics provided by that approach. On the basis of 1D continuum damage models it is shown that, by introducing some ...
Sistema de baixo custo para nucleação de pré-trincas por fadiga em corpos de prova de tenacidade à fratura
(ABM, ABC, ABPol, 2001-07)
Fracture toughness testing becomes a very important parameter for mechanical design and maintenance of parts and structures. This work presents the design and construction of a machine device to perform the pre-crack ...
Fracture and failure behavior of jute fabric reinforced polypropylene. Effect of the interface modification
(Smithers Information Ltd, 2006-12)
The tensile fracture and failure behaviour of jute cloth (25 wt.%) reinforced polypropylene (PP) composites were studied as a function of certain interface modification procedures. The latter covered esterification of the ...
Mechanical stratigraphy and structural control of oil accumulations in fractured carbonates of the Irati Formation, Parana Basin, Brazil
(Soc Brasileira Geologia, 2020-01-01)
Fracturing analysis of low-permeability rocks as reservoir analogs have increased in recent years. The main mechanism involved in the development of secondary porosity in low-permeability, fine-grained limestones of the ...
Effect of the number of screws on the stability of locking mandibular reconstruction plates
(2013-03-25)
Atrophic mandible fractures are frequently a challenge to stabilize. This study evaluated, through mechanical testing in vitro, the number of locking screws that is sufficient to withstand loading when applied with a locking ...
