Fracture Characterization of Glass-Sheep Wool Fabric Reinforced Epoxy Hybrid Composite using Stacking Sequence
Abstract: AbstractFibre-reinforced composites are advance market share in structural applications, but further growth is restricted by their lack of toughness. Fibre hybridization is a hopeful approach to toughen composite materials. By combining two or more fibre types, these hybrid composites offer a better balance in mechanical properties than non-hybrid composites. The research and advancement in the area of natural fiber composites (NFC) are gaining more importance due to its eco-friendly, biodegradable, …

An Overview of Recent Advances in Viscoelastic Surfactant based Fracturing Fluid Technology
Abstract: High percentages of oil and gas wells are hydraulically fractured worldwide in order to make economically producible at an efficient production rate. Cross-linked polymer fluids are in use for decades to stimulate oil and gas wells. Even though these fluids exhibit exceptional viscosity, thermal stability, proppant transportability and fluid leak-off control; extensive formation damage by polymer residues demanded a clean fracturing fluid technology. New generation of fracturing fluids based upon …

Fractured Femur – A Birth Injury!
Abstract: Birth injuries are an important medico-legal issue. It is a wide held belief that caesarean section is a safe mode of delivery. However, in certain difficult cases, injury may be sustained by the newborn as a result of the mechanics of delivery. Some of these less common injuries can be easily missed at birth leading to significant late morbidity. If diagnosed and treated in time, the outcome is usually good. …

Effect of Chemically Treated Plant Cellulose on Mechanical, Fatigue and Fracture Toughness Behaviour of Polyester Composite
Abstract: In this research study, the effect of chemically treated plant cellulose on the mechanical, fatigue, and fracture toughness behaviour of polyester composites was investigated. Ramie plant cellulose fibers were used as the reinforcing material, and polyester resin was used as the matrix material. Three different chemical treatment processes, namely alkalization, acetylation, and etherification, were used to adapt the superficial chemistry of the fibers and advance their compatibility with the polyester …

Experimental Exploration of Crack and Damage Dynamics of Hybrid FRP Nano Composites
Abstract: Fiber-reinforced polymer (FRP) composites have become essential materials in modern engineering structures because of their excellent strength-to-weight ratio, corrosion resistance, and adaptability in design. Among different fracture modes, Mode I interlaminar fracture where cracks propagate under tensile opening stresses is one of the most critical forms of damage in layered composites. Since delamination occurs within the matrix-rich regions between plies, improving the matrix properties plays a key role in enhancing …

Computational Modeling of Fluid Flow through A Fractured Media under Overburden Pressures
Abstract: Computational analyses were conducted to investigate fluid flow characteristics of a real fractured media. Finite element (FE) and computational fluid dynamics (CFD) analyses were implemented to carry out these computational analyses. The fractured media was exposed to external pressurization to predict permeability and asperity deformation. Furthermore, a series of CFD-FE analyses were also conducted to determine the reduction in permeability of the fractured media under the external pressure. An elastic-plastic …

Biomechanical comparison of Schanz screws placement modes-how can stability by external fixation be raised?
Abstract: AbstractBackground: At present, external fixators are being used widely in open fractures of the long bones and also accepted as a temporary skeletal stabilization even in closed fractures. Therefore, it is essential to increase the stability which is provided by those devices for good outcomes. We hypothesized prior to the study that the greater is the distance between the Schanz screws inserted in each fracture fragment, the higher is the …

Fractural Mechanics Crack Propagational Study on Different Material And Different Crack Location of weld joint in ANSYS
Abstract: AbstractThere have been spectacular failures made of ductile material. The structure as whole will remain as brittle only until the load is applied it will have elastic response it will not have plastic response. But near the crack tip there will have plastic zone and plastic zone indicates flow crack is going to behave for the present study analysis is carried out on crack near weld joint and three different …

Treatment of open comminuted fracture of the cruris and infectious nonunion by ablating focuses and prolonging bones
Abstract: AbstractThe crural fracture occupies widely accompanying by trauma and if the bone should be occupied traumatic osteomyelitis, the treatment is very difficult. In general, because inflammatory disappear and the wound closed, when the therapy of facture take place, so the day of treatment is delaying and occupying ununion of bone by secondary infection. The objective of this study was to evaluate the method of ablating focuses and prolonging bones in …

Breathing prediction of fracture deviated wellbore through flooding mechanism
Abstract: Wellbore breathing is a common occurrence during drilling operations, but the down hole mechanism and how it manifests itself in surface and subsurface processes, is not well understood. It often result in a drilling fluid gain at surface and are misidentified as a kick, resulting in unneeded shut in periods and associated non-productive time (NPT). Further, misidentification of wellbore breathing as underbalance often results in increases in mud weight, which …

Numerical Investigation of the Osmatic Flow Impact on the Load Recovery and Early Well Performance
Abstract: The complexity of shale system coupled with the mystery of low fracturing fluid recovery has puzzled many researchers. Field reports from hydraulic fracturing operations performed on shale formation have highlighted the low recovery of the fracturing fluid. The fate of the hydraulic fracturing fluid is still controversial issue. However, literature has attributed the low load recovery to either trapping into the natural or created micro-fracture or imbibition to the matrix. …

White Eye Orbital Blowout Fracture, A Case Report
Abstract: The "white eye" blowout orbital fracture is an easily missed injury in oral and maxillofacial trauma due to its discret clinical and radiographic presentation. The elastic nature of bone in paediatrics makes it the most commonly encountered type of orbital fracture in these patients. The consequences of delayed diagnosis and treatment might include severe illness. Therefore, it should be early recognized to ensure optimal treatment and favourable outcomes. The authors …
