Abstract

It is important to study the Behaviour of high-density polyethylene (HDPE) under notch effects as it is widely used in industrial applications (Qi, 2018). However, there are only a few studies on the Behaviour of HDPE with defects, this work aims to study the deformation mechanisms under a tensile test experimentally performed on blank and notched specimens at constant speed and room temperature, and by developing our study by simulating HDPE using commercial software code.

Highlights

High density of polyethylene ''high-density polyethylene (HDPE)'' is widely used in industrial applications Because of its lightness, durability, flexibility and its impact resistance, e.g. bottles of HDPE cooling (Qi, 2018)
The uniaxial tensile tests consist in exerting a displacement in the transverse direction of one side of the specimen, the specimen used is of the parallelepiped type for the three tests.In a second step, the experimental results obtained with the MTS series 40 traction machine and the TWE MTS control software will be compared with the numerical results

Summary

INTRODUCTION

High density of polyethylene ''HDPE'' is widely used in industrial applications Because of its lightness, durability, flexibility and its impact resistance, e.g. bottles of HDPE cooling (Qi, 2018). Industrial packaging and other applications (Ngoc Giang, 2015) takes into consideration the effects of defects, which have changed the Behaviour of HDPE from ductile to brittle. The uniaxial tensile tests consist in exerting a displacement in the transverse direction of one side of the specimen, the specimen used is of the parallelepiped type for the three tests (blank, V notch, U notch).In a second step, the experimental results obtained with the MTS series 40 traction machine and the TWE MTS control software will be compared with the numerical results
