Local deformation and temperature rise in tensile tests of PLA composites

Abstract

Local deformation in tensile tests of polymer material is important because of necking. Beside this, it is necessary to considering temperature rise because temperature rise affects strain and stress. We carried out tensile tests of PLA/PCL composites at 2 deformation speed. We examined about strain rate of necking area dependence by using digital image correlation and temperature rise by using infrared camera.
