Abstract(s)

The 2nd Symposium on Integrated Computational Tools for Advanced Manufacturing held within the 14th International Conference of Numerical Analysis and Applied Mathematics, in Rhodes, Greece, from September 19 to 25, 2016. This symposium is a relevant forum for the scientific exchange of multidisciplinary issues related to integrated computational tools for advanced manufacturing. It contains five reviewed papers, covering important research topics, such as numerical modelling using finite element method, computer-aided engineering, manufacturing technologies and optimization using evolutionary algorithms. Four papers related to numerical modelling using the finite element method were presented and covered four main areas: 1) structural optimization, 2) prediction of fruit damage, 3) computational fluid dynamics applied to helmet design, and 4) mould design and injection moulding process. The obtained results suggest a significant improvement regarding the state of the art. On the first one, an important research work was developed on numerical modelling of structural mechanical behaviour. Geometric and multimaterial parameters of wind towers were optimized. A mono and multimaterial combination using steel, concrete and polymer concreted was studied through static, modal and buckling analyses. The numerical model developed allows the optimization of wind towers design, reducing the structural mass and cost involved in the construction of this kind of structures. In the second one a nonlinear finite element model was developed to mimic accurately apple mechanical behavior whereas its nonlinear geometrical and material properties were considered. The numerical results obtained were compared with the experimental ones allowing the validation of the proposed numerical model. The third work used a computer fluid dynamics analysis to study drag force acting upon two helmets for wheelchair racers. Using this approach personalised 3D computer models of helmets were obtained, aiming to optimize athlete’s performance through the customization of 3D computer model of helmets. The forth is related to mould design and injection moulding process. In this work an integrated computer tool approach was developed taking into account the design, computer simulation and manufacturing processes. Biopolymer injection process was simulated predicting biopolymer injection parameters. In the fifth reviewed paper a novel global optimization framework using evolutionary algorithms is presented. The problematic of form follows energy was studied through this framework. Optimal 3D shape as a function of the solar energy location was calculated. This procedure adds value to the sustainable architectural building.
