...J. Langus; P. Šuštarič; T. Rodič Purpose The purpose of this paper is to evaluate the effect that polymer coat has on the impact behavior of grinding sphere and to find possible subsection of parameter space in which grinding sphere wear could be reduced. Design/methodology/approach Numerical...

...Valentina Salomoni; Gianluca Mazzucco; Carlo Pellegrino; Carmelo Majorana Purpose The purpose of this paper is to investigate the bond behaviour between fiber reinforced polymer (FRP) sheets and concrete elements, starting from available experimental evidences, through a calibrated and upgraded 3D...

... of the crystallographic planes on the predicted mechanical behaviour and texture development of polyethylene prior to failure. Polymers Crystallization Stress (materials) Modelling Algorithms For the discrete time implementation, a velocity gradient [L¯] is prescribed. As done in crystal plasticity...

...P.S.B. Zdanski; M. Vaz, Jr; G.R. Inácio Purpose Numerical simulation of polymer injection processes has become increasingly common in mould design. In industry, such a task is accomplished mainly by using commercial packages. Owing to the complexities inherent of this class of problems, most...

... Emerald Group Publishing Limited 2007 Polymers Crystallization Optimization techniques Chemical kinetics The goal of this study is to apply the genetic algorithm inverse method to the determination of crystallization kinetics parameters. Starting from the Avrami model's hypotheses...

...Qin Sheng; Fred F. Farshad; Shangyu Duan In this study, a three‐dimensional (3D) flow model is used to approximate the crystallinity gradients of slowly crystallizing polymers developed in the injection molding process. A generalized second order parallel splitting formula is constructed to achieve...
