“…The ultimate tensile strength for all laminates is in the range of 27 MPa to 45 MPa. On another hand as per Gojko Vladi et al [37] the maximum tensile strength of ABS plastic is 31.39 MPa with strain at break is 2.57% and 43.8 MPa according to Fatima Nassih et al [38]. The modulus of elasticity of plasticized (flexible) PVC ranges from 1 to 1800 MPa [4].…”

Natural-based composites are gaining popularity among composite makers and end users because of their biocompatibility, low cost, and abundance. The influence of Glycerin as a plasticizer in various percentages ranging from 3% to 12% on Tensile, Flexural, Impact, Inter-laminar Shear Strength (ILSS), and Hardness characteristics of a Kenaf-Jute hybrid polyester composite, which is fabricated using hand layup followed by the hot press method, was investigated in the present study. It was observed that a 6% Glycerin concentration in polyester Kenaf-Jute composite outperformed other composites in Tensile, Flexural, and Impact strengths in the range of 2 to 73%. This is evident by analyzing SEM images that better physical bonding between the Kenaf-Jute fibers with modified polyester resin using Glycerin. As the Glycerin content in the composite increases, the Hardness decreases when compared to without modified polyester.

The advancement of polymers continues to expand relentlessly, playing an increasingly significant role in our daily lives. Ongoing developments in polymer science have revolutionized numerous industries and brought about a multitude of applications. From mass-market industries to high-performance sectors, polymers are omnipresent in all aspects of our lives, highlighting the need for a more rigorous understanding of their properties, characteristics, and behavior. In this context, two approaches have been adopted to estimate the critical failure time of ABS specimens: one involving virgin specimens and the other artificially pre-damaged with notches of varying diameters. The first approach is based on damage mechanics and utilizes a modified damage model, while the second approach relies on fracture mechanics and utilizes the Griffith theory to estimate the critical notch from which the specimens should be rejected. These two methods allow us to track material degradation and predict the moment when damage acceleration occurs. This technique provides industrial stakeholders with the opportunity to implement a preventive maintenance strategy.

“…This pressure gradually decreases as the number of cyclic solicitations increases until rupture occurs. If the fatigue test is stopped before the final rupture, and the tube undergoes a burst test, the rupture occurs at a lower residual ultimate pressure, Pur, situated between Pu and Pa, corresponding to the bursting pressure of the most stressed specimen By analogy with cyclic behavior, considering a notch in a tube as a lifespan that consumes an equivalent number of cycles equal to Ni, we conducted burst tests on damaged specimens at various levels of artificial damage [21][22][23][24][25][26].…”

In several industrial applications, plastic, composites and ceramics replace a number of metallic structures such as copper, aluminum and steel. Most recently installed piping water and gas systems in the world are made of thermoplastic due to its advantages, for example, low cost, ease of fabrication and corrosion resistance. In this work, the chosen material is chlorinated polyvinyl chloride (CPVC); the best one used to transport cold and hot water beside simplicity of installation. Notwithstanding, the pipes in service are submitted to different loads, related to environmental, thermal and mechanical effects which procure to mechanisms of degradation. The aim of this article is to assess the effect of the defect on CPVC pipes, through a study of the defect criticality in the form of semi-elliptical, then the ability to predict defected pipes residual life. Therefore unexpected and sudden failure caused by pipes accelerated damage. Therefore, we performed burst tests on both pre-damaged CPVC pipes and virgin ones. To lead our work in this paper, interested in the damage modeling and the failure analysis of CPVC pipes, we adapted the model of unified theory static damage, originally developed in fatigue. We used burst pressure tests to identify the limits of three damage progression phases and, in turn, to calculate the critical life fraction at which these flaws become harmful. Furthermore, we identify the critical depth for the studied defect. These results and techniques enable industrialist s to anticipate this structures service life under these conditions after that set up a robust system of maintenance to ensure a reliable and safe functioning of the structure.
