“…The tests were carried out under the conditions of air and ambient temperature (≈ 20 to 24 ° C.) on a ZwickRoell type machine with a load cell of 2.5 KN. For material characterization, unixial tensile tests were performed according to ASTM D638-03 [6], ASTM D 882-02 [7] and ASTM D5766M [8], Figure 1 below shows the drawings of definition of the test pieces used for the tests: Subsequently, we studied the effect of defect on the mechanical behavior of the material, and to achieve the objective we have created a geometric defect in the form of a semicircle ranging from 1mm to 18mm, Figure 2 shows the shape default.…”

The development of polymers has not stopped growing and taking more and more emphasis in our lives. From high-performance industries to mass-market industries, polymers are ubiquitous in every aspect of our lives, from where comes the pressing need to know their properties, characteristics, and behaviors more rigorously. This work is based on a study of the mechanical characterizations of thermoplastic polymers under the effects of damage. To serve this purpose, an experimental study was carried out on thermoplastic ABS (Acrylonitrile Butadiene Styrene) specimens. At first, we worked on altered specimens to define the mechanical characteristics of our material such as the elastic limit, the stress maximum, the breaking stress and the Young's modulus. On the one hand, and on the other hand we have created geometrical defects (discontinuity) on specimens in (ABS), to have the effect of defects on the mechanical characteristics of the material, afterwards a study of damage carried out by two methods to determine the critical fraction of life. To determine the lifetime of the ABS.

“…Therefore, the damage theory aims to studying the evolution of the material behavior of the virgin state to the initiation of macroscopic cracks of the size of the representative volume element [30][31]. There are numerous types of laws in the literature that can model the damage from experimental results, but we limit ourselves here to the ERISMANN model [32].…”

Most Chlorinated Poly Vinyl Chloride (CPVC) resins contain 63-69 % chlorine, in particular those used for the extrusion of plumbing tubes, due to this chlorination of basic PVC, CPVC offers a mixture of corrosion resistance and low installation costs for its main applications requiring service in non-ambient conditions. CPVC replaces copper owing to its economic gain and by virtue of its pressure resistance characteristics. In this article, we have been interested in fracture analysis and damage modeling of CPVC tubes by subject CPVC samples to burst pressure tests. We performed a set of burst tests on virgin and artificially damaged CPVC pipe at different notch lengths, then submitted the specimens to burst pressure tests, in addition to recording the pressure and time during these tests for use in conducting the study. The results of the burst tests were exploited to estimate the damage and reliability of the material, these two parameters allow us to follow the degradation of the pipes used; subsequently, we determined a new relationship between these two parameters through the fraction life. This makes it possible to predict the moment of damage acceleration and to intervene at the right time for engaging predictive maintenance.

“…Through correlation with the cyclic loading, the residual energy at break of a thermoplastic material decrease because of temperature decreasing, consequently, in this article based on the Miner's law we took on a modified approach. [11] The damage calculates by the new method utilizing residual energy is compared to Miner damage [10], the latest is more critical when the temperature decrease.…”

The Chlorinated Polyvinyl Chloride pipes used for the supply of cold and hot water are designed and manufactured for a 50 years predictive life, but defects and harmfulness may occur during the transport process, storage and operation of tubes that significantly affect these forecasts. This work deals with the study of the mechanical behavior of Chlorinated Polyvinyl Chloride (CVPC) specimens subjected to tensile tests under the effect of temperature. Moreover, a study of damage evolution by the ultimate energy makes it possible to determine the three stages of the lifetime of the test pieces studied. On the basis of the stress-strain variation curves plotted from the experimental results, the critical value of the fraction of life corresponding to the acceleration of the damage was determined.
