Effect of loading rates on fracture toughness of HDPE / Hassnol Ishraff Mohd Yusof

The objective of this project is to examine or to study the effect of various loading rates applied to a High Density Polyethylene (HDPE). Two types of tests have been conducted. For the Quasi-static test, the experiment states a method for determining the opening mode plane strain fracture toughnes...
