1. 1. Strain rate-dependent mechanical properties of high-density polyethylene(HDPE)

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Oscar Andersson; Alexander Wiklund; [2022]
   Nyckelord :HDPE; strain rate; DIC; inverse calibration; Abaqus; HDPE; töjningshastighet; DIC; Inverskalibrering; Abaqus;

   Sammanfattning : In today’s packaging industry HDPE is widely used and correct understanding of itsproperties and how to model them is of vital importance. HDPE is a semi-crystallinepolymer with a known strain rate dependence, that is a higher yield and lower strainto failure at higher strain rates. LÄS MER
