Experimentally Verified Mathematical Model of Polymer Plasticization ...
...The mathematical model of the polymer plasticization in the reciprocating screw injection moulding machine is presented in this paper. Methods of calculation of the most important flow characteristics, such as the solid bed profile, the pressure and temperature profiles, the mass flow rate, the power demand, the screw torque and the energy consumption were analysed. According to the ......

Mathematical Model for Prediction and Optimization of Weld Bead ... - MDPI
...To assure that the established model can predict and control the weld bead shape in actual application, it should test the accuracy of the mathematical model. The test experiments were executed by assigning diverse values for experimental variables within their working limits, but distinguishing them from the values of the design matrix....
