Use of Digital Image Correlation to study the effect of temperature on the development of plastic instabilities in a semi-crystalline polymer

30 Nov 2018 Farge Laurent LEMTA André Stéphane LEMTA Boisse Julien LEMTA

The plastic deformation processes that occur in a tensily deformed High Density Polyethylene specimen were studied from full-field strain and strain rate measurements obtained by 3D DIC (Digital Image Correlation).The tensile tests were performed every 10{\textdegree}C from room temperature to 120{\textdegree}C . For temperatures below 60{\textdegree}C , it is shown that the strain localization effect becomes less pronounced when the temperature increases... (read more)
