Strain Field Measurement on 3D Surfaces: Application to Petaloid Base of Pet Bottles Under Pressure
Source abstract
Abstract
The main goal of this paper is to provide an identification tool for the orthotropic elastic properties in the 3D regions of PET bottles. We focus on the behavior of the petaloid bases when bottles are submitted to an internal pressure. A stereo correlation software has been developed to evaluate the membrane strains. Two bases named VS (small valley) and VL (large valley), which highlight different behavior at the ESC (environmental stress cracking) test, are compared with this tool. Coupled with a finite element simulation managed on the same bases, these results allow the identification of the induced mechanical properties.
