20.500.12556/RUL-98332 Injection molding simulation with solid semi-crystalline polymer mechanical behavior for ejection analysis Injection molded products, produced from semi-crystalline polymers may include undercut features which can introduce distortion to the shape of the product during ejection. A thermo-mechanical modeling approach for simulating these advanced ejection problems is developed. The approach is formed by combining a method for three-dimensional residual stress prediction and an advanced material model for modeling the solid visco-elasto-plastic mechanical behavior. The task of this work is to assess, by analyzing a plaque-like product, the performance of the approach in the absence of the distortive ejection effects. The numerically predicted product shrinkage and mass at different packing pressure settings are compared to experimental results. The effect of packing pressure on product shrinkage and mass was reproduced by the model and the final residual stress field was found to be in accordance with the expectations. This confirms that the methodology could be used to analyze advanced ejection problems. injection molding numerical simulation residual stresses shrinkage ejection true false false Angleški jezik Angleški jezik Delo ni kategorizirano 2017-11-27 14:11:50 2018-02-28 10:58:09 2022-08-12 14:44:51 0000-00-00 00:00:00 0 0 0 4111-4124 9 93 2017 0000-00-00 PostprintKoncna NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2018-11-27 519.62:678.027.74 10.1007/s00170-017-0847-3 Clanek2b_04_UL_REPO.pdf Clanek2b_04_UL_REPO.pdf 1 058E9675E5A8E35B25F4621D783956A5 2d2f4897f4403051bf73a09ed5b0a06847ec73db6676be860b4d2c649ddf903e 5cbbfaae-a1b4-11eb-a523-00155dcfd717 20.500.12556/rul/fc8dc565-c036-4654-92eb-9e98743b6d2b https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=107571 Fakulteta za strojništvo 0 0 0
