dc.description.abstractThis thesis explores the mechanical properties of polymers, focusing on their behaviour under compression load. It begins by discussing the basics of polymers, their classification, and historical background. The study employs compression testing and Finite Element Analysis (FEA) to analyse polymer behaviour, highlighting the importance of nonlinear material models. Additionally, it investigates the implications of polymer behaviour in extreme conditions and high-rate mechanical research, along with tensile properties, strain hardening phenomena, and shear properties. The thesis contributes to understanding polymer mechanics for engineering design and innovation. The experimental part of the thesis focuses on compression testing methodology and FEA validation. It utilizes electromechanical testing equipment and software, along with a polymer specimen (Celanese's GUR 4150). Calibration, compression tests, and FEA analysis are conducted, demonstrating consistency between experimental and simulated results. The Calibration of the equipment in necessary to get the required results for the given experiment and I have explained the process of it in the thesis. The compression test is itself a main part of the whole system. We will put the subject under the machine before and after taking all the measurements and we will compare it. I will be able to conclude the Stress-Strain curves from the values and we will subject it to force until the breaking point post-processing confirms the accuracy of the experiment and in simulation, emphasizing the importance of material selection and testing methodologies for industrial applications. In simulation we will use the same process, but I will first draw the structure in Femap software, and we will set all the necessary conditions to perform the simulation. We will apply loads on the given structure and start the simulation. The results we will get from the simulation we will draw the stress-strain curves and will subject it to the comparison of the measured and simulated results which you can find it in the thesis. From that we can show the behaviour of polymers acting under compression load.
