“…However, the maximum temperature of 90 Deg C inside the cooler will not affect the surface of the shroud, which was sealed with sealing strip and clip-on gasket. Also the work by Amir Bozorg-Haddad and Magued Iskander, 2011 [8] supports for the life of the HDPE under creep, will have the deformation of 2% by 100 years…”

“…Ashby, 2005,[7] has suggested the possible methods in the material selection for any given application, by converting the requirements in to an equivalent derivative. For computing thermal conductivity of particle reinforced epoxy composites, Ansys is used as the finite element analysis tool [8]. Work by Amir Bozorg-Haddad and Magued Iskander, 2011 [9] gives the relation between the life of the HDPE material subjected to creep.…”

Use of alternate material is always a continuous development in any industry. Such proposals aim at weight reduction, improve life of the components and reduce the components cost. When it comes to the compressor application, there is always a challenge in replacing such parts with polymers, especially on the canopy parts. This study aims at replacing the material of screw compressor canopy with a suitable material with the target of weight and cost reduction, without compromising the functional requirements. Suitable material for the shroud assembly is chosen using the theoretical method and validated using finite element analysis. Suitable process is chosen for the Proto-type shroud from the proposed alternate material (HDPE) and tested in the real-time environment

“…This method has already been established in the geosynthetics sector by Thornton and standardized in ASTM D 6992 (for applications see). For several years, the intention has been to transfer this testing method to other types of plastics such as polypropylene under uniaxial tensile or compressive stress . In each method described so far, however, the measurement is carried out globally, including the whole volume of the respective test object, and local processing‐related differences of creep behaviour cannot be displayed.…”

[6][7][8][9] In each method described so far, however, the measurement is carried out globally, including the whole volume of the respective test object, and local processingrelated differences of creep behaviour cannot be displayed. The method describes the local long-time creep behaviour for various polypropylene materials under the application of the SIM to the recording macroindentation, as elucidated in the following.…”

Summary The Stepped Isothermal Method (SIM) is a relatively new method for accelerated determination of the creep behaviour of polymers. The need for such a new method arises from the fact that for modern plastic components such as pipe systems minimum lifetimes of 50 years and more are achieved. The analysis of creep applying conventional methods of testing over such long periods of time is not reasonable from an economic point of view. This forms the basis for the development of accelerated procedures such as SIM. Plastic components can exhibit creep characteristics to be a function of the position due to processing. Such position‐dependent creep behaviour cannot be imaged by volume‐sensitive creep tests such as SIM under uniaxial tensile load. Therefore, SIM was implemented by means of recording macroindentation to characterize the local long‐time creep behaviour and the expressiveness of this method for different polypropylene materials was shown in this study.

“…SIM is a well‐established method for the accelerated product testing of geosynthetics, standards have been published for both tensile creep (ASTM D 6992) and compressive creep (ASTM D 7361). It was successfully applied for creep studies in polypropylene (PP) , aramid fibers , and high density polyethylene pipes .…”

Rotationally moldable linear low density polyethylene (LLDPE) is one of the most popular materials used for rotational molding. Yet, incorporation of additives is necessary to improve the mechanical, visco‐elastic, thermal as well as melt flow properties of LLDPE. In this article, the influence of fumed silica (FS) nanoparticles on the mechanical properties viz. tensile, flexural, and impact strengths of rotationally moldable LLDPE is investigated. The microstructural studies using SEM were conducted to study the dispersion of FS in LLDPE and correlated with the mechanical properties of the nanocomposites. Dynamic mechanical analysis (DMA) were also carried out to find the time–temperature dependent mechanical properties viz. storage modulus (E'), loss modulus (E”), and tan delta between 1 and 8 wt% of FS. DMA studies were extended to perform accelerated stepped isothermal creep studies to find out the influence of FS in creep strains. POLYM.
