A lecturer in Biomedical Engineering Department published a scientific research in a sober international journal on Design and Modeling of a Soft Artificial Heart by using advanced design programs
The lecturer at the Department of Biomedical Engineering at the University of Technology, Dr. Saad Mahmoud Ali / the scientific assistant of the Department, published a scientific research in the Journal of Materials Science and Engineering, which is a discreet international journal of Scopes reiters entitled “Design and Modeling of a Soft Artificial Heart by Using the SolidWorks and ANSYS”.
The research was published in volume (671), Issue (1), January 2020, whereby the researcher showed that investigating the biomechanical behavior of a novel soft artificial heart is a hard task as such things are very complicated in terms of material properties, geometry and engineering performances. The work focused on developing, designing and modeling a new generation of industrial heart that is low cost, easily operable, and in the size and low energy consumption, and durable soft artificial heart intended to replace an original heart permanently while the age of the best produced artificial heart is less than five years. Numerical simulation and investigation of the artificial heart were implemented using SolidWorks 17 and ANSYS 15.7, with a Multiphysics static structural model, fluent fluid flow (CFX), and fluent fluid poly-flow (CFD) analysis systems used in order to determine the dynamic response and effects of pressurized blood on heart performance during blood flow cycles. The biomechanical modeling and analysis of the soft artificial heart were implemented using the finite element modelling in ANSYS R18.0. To improve and verify the biomechanical performance, Design Expert 11.0 software and a response surface methodology (RSM) technique were used. The simulation results showed that as maximum levels of absolute pressure were applied on the ventricles and air pressurized chambers, the performance of the designed soft heart remained to perform in complete secure. The results also showed that strain energy, total deformation, maximum principal elastic strain, stress and fatigue safety factors, and fatigue life all reached their optimum values when using the SIBSTAR 103T with polyetherimide/silicone (PSN4) Nano-composite elastomers.

Two Lecturers staff at the Department of Biomedical Engineering at the University of Technology, Professor Dr. Jinan Sattar Kashan and Dr. Saad Mahmoud Ali / the scientific assistant of the Department, published a scientific research in the Journal of Materials Science and Engineering, which is a discreetinternational journal of Scopes reiters entitled “A biomaterial for scaffold applications: Thermal properties analysis of a PSZ-TiO2 /HDPE system”.
The research was published in volume (671), Issue (1), January 2020, whereby the researchers showed that the nanomaterial mainly composed of high-density polyethylene matrices reinforced with titanium dioxide (TiO2) as a promising biomaterial due to its superior properties. In this work, an attempt was made to study the effects of six biocomposites hybrid Titanium dioxide (TiO2) and yttria-stabilized zirconia (Y-PSZ) samples reinforced with high-density polyethylene (HDPE) matrices, split into two groups, in terms of withstanding the daily activity loads imposed by human bone grafting and repairs. The fabricated composites were investigated using the hot-pressing technique at different compression pressures and compounding temperature. To achieve characterization, thermal analysis of the process using differential scanning calorimetry (DSC) techniques was undertaken. To improve and verify the results, Design Expert 11.0 software and a response surface methodology (RSM) technique were used. For both nanofabricated types, the results showed that an increase in TiO2 ceramic filler from 1% to 10 %, caused percentage crystallization to increase by 14.58%. The heat of system fusion for the second fabricated system also decreased by 11%. These results show that this addition reduced the heat of system fusion by 109% compared with previous studies. The glass transition (onset) and end (melting) temperature also increased with increases in the applied compression pressure and hot-pressing temperature. The differential scanning calorimetry (DSC) scanned curves and the 3D atomic force microscopy (AFM) microstructure and granularity distribution images for both fabricated nanocomposite systems clearly showed that the interconnections between the filler’s ceramic nanoparticles within the polymeric matrix offer high surface roughness values due to the excellent nanofiller particle distribution within the polymeric matrix.
