Moldex3D Announces the Article Publication on Prestigious Journal of Rheology®

on 01/27/2016

Hsinchu, Taiwan—January 27, 2016 – CoreTech System Co., Ltd. (Moldex3D), the leader in 3D CAE simulation solutions for plastic injection molding industry, is pleased to announce today that our paper was accepted and published by a reputable publication of Journal of Rheology® in its latest issue. According to SCI (Science citation index) ranking, the Journal of Rheology® is among the top 5 publications out of 137 publications in the category of mechanics and is considered as one of the most important leading publications in Rheological Fundamentals of Polymer Processing.

The published paper, entitled “An Objective Tensor to Predict Anisotropic Fiber Orientation in Concentrated Suspensions,” was authored by Dr. Ivor Huan-Chang Tseng, Program Manager in the R&D Division of CoreTech System (Moldex3D). In this paper, Dr. Tseng investigates the objective issue of a new fiber orientation model, iARD-RPR with great efforts and proposes a new objective iARD tensor, which passes the classic rheological rule of Euclidean objectivity, namely, material frame indifference. The objective model is more reliable to accurately predict the anisotropic fiber orientation behavior in injection-molded parts of complex geometry, for example, parts with rib or hole features, as well as parts with varying wall thickness or changes in flow direction.

Thus, as the first step, Tseng differentiates the differences between the original Phelps–Tucker anisotropic rotary diffusion tensor and the objective iARD tensor via computing their first invariants. Then, the accuracy of this new improved iARD model with an objective tensor in predicting a distinct, broader core-shell orientation structure of injection-molded long-fiber composites is further validated by a careful experimental verification.

The paper received an outstanding recommendation from the journal’s peer reviewers and was highly recognized for its scholarly merits to further the research study of fiber orientation predictions in the field of rheology. “It is indeed a great pleasure to be recognized by prestigious Journal of Rheology®,” said Dr. Tseng. “One of the core missions we do here in R&D Division of CoreTech System (Moldex3D) is to contribute our research efforts in advancing and applying rheology, both in theoretical and experimental aspects into the development of Moldex3D software capabilities. The close-to-reality molding results predicted by Moldex3D will truly benefit a wide range of practical applications using fiber-reinforced composites by providing accurate and reliable analyses in solving complex design and manufacturing challenges.”
