1. 1. Material characterization of long-term stress relaxation in a semi-crystalline polymer material : An experimental and numerical study

   University essay from Blekinge Tekniska Högskola

   Author : Jakob Görtz; [2021]
   Keywords : Abaqus; MCalibration; PRF; HDPE; Stress relaxation; Long-term testing; Theoretical expressions; Material calibration;

   Abstract : As the plastic and packaging industry is looking to increase the longevity of plastic products as well as recycling used material, there is a need to understand how material properties respond and change during long periods of mechanical loading. Physical tensile experiments on thin plant-based High-Density Polyethylene (HDPE) are conducted with the intent of capturing relaxation behavior from a short-term (1-3 hours) and long-term (29-56 days) perspective.

3. 2. Effect of strain rate on continuum and pre-cracked polymer failure

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Author : Pratik Rajesh Powar; Ashkan Raeisi; [2021]
   Keywords : DIC; LDPE; MCalibration; Polymer; Strain Rate;

   Abstract : The main intention of this thesis work was to investigate the effect of strain rate on continuum and pre-cracked polymer failure. Low-Density Polyethylene (LDPE) was chosen to study experimentally and numerically. In order to cover wide range of strain rates, four specific strain rates were selected for the uniaxial tensile tests. READ MORE
