“…The authors concluded that normalized crack density rather than crack density was a more appropriate parameter for use in predicting cracking damage. Frost and Cervenka (1994) studied the influence of loading frequency in predicting the long term fatigue behavior of a GRE pipe. They concluded that the prime failure mechanism observed for short and long term fatigue was leakage as a result of matrix cracking.…”

“…Limited studies have reported on this procedure. Hull et al (1978) and Frost & Cervenka (1994) both reported on the UEWS test and observed that matrix cracking is consistently associated with non-linearity in stress strain responses. The intention of the UEWS test is to identify, by examining the stress-strain response, a stress level below which damage growth is either negligible or at least sufficiently low to prevent long term failure in the design life.…”

“…The failure behavior of filament wound GRE pipes subjected to biaxial load has been the subject of numerous experimental and modelling investigations spanning decades, as demonstrated in the literature (Bachtiar, Sapuan, & Hamdan, 2010;Carvalho & Marques, 2007;Frost & Cervenka, 1994;Gibson, Saied, Evans, & Hale, 2003a, 2003bHale, Shaw, Speake, & Gibson, 2000;Hull, Legg, & Spencer, 1978;Jeffrey, Tarlochan, & Rahman, 2011;Meijer & Ellyin, 2008;Mertiny & Ellyin, 2006;Ravi Sankar, Srikant, Vamsi Krishna, Bhujanga Rao, & Bangaru Babu, 2013;Salleh, Yusop, & Rosdi, 2013;Tarakcioglu, Gemi, & Yapici, 2005). The majority of such investigations have emphasized failure envelopes, fatigue strength, leakage and the associated deformation of angle ply laminates similar to those used in GRE pipes.…”

This paper presents the modelling of the stress strain response of glass fiber reinforced epoxy (GRE) composite pipes subjected to multiaxial loadings at room temperature (RT). This particular modeling work was developed to predict the non-linear stress strain response caused by the fatigue cyclic and static loading in the multiaxial ultimate elastic wall stress (UEWS) tests by considering the effects of matrix cracking within the laminates. The UEWS test, whilst not yet standardized, appears to offer an attractive alternative to existing procedures of qualifying GRE pipes. The ply properties initially expressed as a function of crack density were computed as a function of increasing stress and strain using shear lag approximation. The results show that the model developed from the classical laminate theory which takes into account whether the effects of transverse matrix micro-cracks on stiffness and strains is capable of predicting the resulted elastic properties. The predictions are found to be in good agreement with the data from multiaxial UEWS tests on ±55° filament wound glass-reinforced epoxy pipes.Keywords: Stress strain response; multiaxial loadings; composite pipes; cyclic and static loading; crack density. INTRODUCTIONThe failure behavior of filament wound GRE pipes subjected to biaxial load has been the subject of numerous experimental and modelling investigations spanning decades, as demonstrated in the literature (Bachtiar, Sapuan, & Hamdan, 2010;Carvalho & Marques, 2007;Frost & Cervenka, 1994;Gibson, Saied, Evans, & Hale, 2003a, 2003bHale, Shaw, Speake, & Gibson, 2000;Hull, Legg, & Spencer, 1978;Jeffrey, Tarlochan, & Rahman, 2011;Meijer & Ellyin, 2008;Mertiny & Ellyin, 2006;Ravi Sankar, Srikant, Vamsi Krishna, Bhujanga Rao, & Bangaru Babu, 2013;Salleh, Yusop, & Rosdi, 2013;Tarakcioglu, Gemi, & Yapici, 2005). The majority of such investigations have emphasized failure envelopes, fatigue strength, leakage and the associated deformation of angle ply laminates similar to those used in GRE pipes. However, whilst most of these studies concentrated on structural failure in composite pipes, the more significant issue of micro structural progressive damage, which leads to the final failure, is less clear. Most of the literature has reported that filament wound composite pipes under fatigue biaxial load failed due to sequences of damage which

“…The first composite alternatives to steel pipelines consisted of composite pipes based on thermoset matrices. The properties of thermoset composites are well known and documented [1]. However, the increasing demands of the oil and gas industry, involving high temperature resistance and the need for damage tolerance and flexibility, often exceed the capabilities of thermosets.…”

This paper describes the analysis of a long length reinforced thermoplastic pipe. For this new class of pipe, which is constructed of a polyethylene liner pipe over wrapped with two layers of non-impregnated twisted aramid cords, peculiar deformation behaviour was observed when a pipe was pressurised. This behaviour was found to be a result of a difference in cord-slack between the two reinforcement layers in conjunction with an unbalanced torsion moment generated by the two reinforcing layers. Cord slack is a certain surplus length of the reinforcing cords relative to the pipe geometry. The cord-slack is estimated for the two different layers and first incorporated into an earlier published model, based on a plane stress characterisation. As no substantial improvement has been achieved by this approach, a new model based on a plane strain characterisation is introduced. This model shows good agreement with the experimentally determined strains for the hydrostatic pressure load-case. q

“…However, corrosion leads to reduced time life of these components and the need for frequent inspection, repairs or replacement. Polymer matrix composite pipes, alternatively, offer advantages over steel tubes for this application due to the corrosion resistance inherent to this type of material and other benefits such as weight reduction [1][2][3][4] . Many types of resins and fiber reinforcement materials are currently used in composites for oilfield applications.…”

Addition of magnetic markers for non-destructive evaluation of polymer composites

Polymer composite pipes are an appealing option as a substitute for conventional steel pipes, particularly due to their inherent corrosion resistance. However, the composite pipes currently used do not allow non-destructive evaluation (NDE) using instrumented devices which operate with magnetic sensors. The present work aims at the development of polymer composites with the addition magnetic markers to allow the application nondestructive evaluation techniques which use magnetic sensors. Glass-polyester composite flat, circular plates were fabricated with the addition of ferrite particles (barium ferrite and strontium ferrite) and four types of notches were introduced on the plates' surfaces. The influence of these notches on the measured magnetic properties of each material was measured. X-ray diffraction (XRD), X-ray fluorescence (XRF) and Brunauer, Emmett, and Teller (BET) nitrogen adsorption were used for the characterization of the ferrite particles. Particle dispersion in the polymer matrix was analyzed by scanning electron microscopy (SEM). According to the results, a particular variation in magnetic field was detected over the region surrounding each type of notch. The results suggest that the proposed technique has great potential for damage detection in polymer composites using magnetic sensors and thus constitute a valuable contribution which may ultimately lead to the development of non-destructive evaluation techniques for assessing the structural integrity polymer composite pipes.
