Experimental Study on Fracture Toughness of HDPE Material with Compact Tension Specimens for Small Vessel

Abstract

Non-ferro materials in use for ship structures require characteristics that meet the requirements. This research conducted a study and testing of High-Density Polyethylene (HDPE) material in the form of plates with type PE 100. The investigation was carried out with mechanical testing to obtain mechanical properties of HDPE. The purpose of this research is to obtain mechanical properties including tensile strength, ultimate strength, elongation, and Fracture Toughness of this material. In this case, the Fracture Toughness value is obtained using a compact tension specimen. The variation given in this research is to provide artificial defects on the side of the material and without any side grooves. Based on the test results, it is known that the yield strength, ultimate strength, and elongation of the material meet the acceptance criteria, and the fracture Toughness value obtained in this test in both variations is 1.64 Mpa. Where this value does not meet the criteria of the fracture Toughness value.
