| Abstract: | A new optical method of DSCM was used to measure the stress-strain relationship and Poisson ratio of PP strapping band, the creep deformation of paper (Kraft)-plastic (PE) composite, the side-pressure deformation of F-corrugated board box. Comparing with traditional measurements, the DSCM shows its characteristics of non-contact, non-reinforced effect, and high precision in entire area. The measuuring sequicement was discussed based on the particularity of the object's mechanics. |
