Design a Constitive Fuzzy Logic Model of Warpage on shape Memory Polrethane Parts, ICAT'19- Proceedings Book E-ISBN: 978-605-68537-4-6978-605-68537-4-6https://hdl.handle.net/20.500.12695/723TARAMAWOSInjection moulding process of shape memory thermoplastic polymers is important for manufacturing of stimuli-responsive plastic parts in mass production. Moulding conditions have remarkable role on the controlling of permanent shape of moulded parts. Warpage is the one of the main factors, which define the part shape quality. A limited number of experimental studies have been conducted to determine the relationship between warpage and moulding parameters. According to the experimental study, injection pressure and cooling time are the most effective parameters on warpage. But, it is very difficult to define an accurate mathematical model that gives the warpage value with respect to injection pressure and cooling time. In this study, the relationship between moulding parameters and warpage was defined as a constitutive model by using fuzzy logic. Fuzzy model consists of two input variables and one output variable. Cooling time and injection pressure were selected as input variables and warpage was selected as output variable for the fuzzy model. The results showed that the model represented experimental results with high confidence.enAttribution-NonCommercial-ShareAlike 4.0 Internationalinfo:eu-repo/semantics/openAccessPermanent shapeWarpageShape memory polymersFuzzy logicConference Object290294WOS:000686210300004N/A
