Title: Analysis of influential factors on the tensile strength of polyethylene using the factorial design
Authors: Velickovic Sandra
Journal: Technical Diagnostics
Issue Date: 2015
Abstract: Experimental results obtained by tensile test on specimens made of high-density polyethylene are presented in this work. Specimens were tested at low temperatures at different tension speeds. Factorial design and regression analysis were used for statistical analysis of the experimental results, more specifically the two-factorial experiment with three levels. By applying factorial design it can be determined which of observed factors have the greatest influence on the tensile strength of the tested specimens. The analysis of the results shows that the greatest impact on Rm has the temperature. There are also shown linear regression equations for the tensile strength parameters in the function of the effective parameters. Applying this method are reduced testing time and reduced costs required for carrying out of the experiment.
