Investigation of the environmental factors' influence on the mechanical properties of plastics

Abstract

A statistical method for the analysis of the experimental results obtained by tensile test on specimens made of high-density polyethylene is presented in this work. The two-factor experiment with three levels was used for statistical analysis of data. Specimens were tested at low temperatures at different tension speeds. By applying this method it can determine which factors have the greatest influence on the tensile strength of the tested specimens.
