The mechanical behaviors of Nylon6 polymer film material are investigated experimentally. A technique, marker identification method, for non-contact optical measurement of in-plane displacements based on correlation analysis is employed to measure the deformation of the film specimens. Based on the uniaxial tension experimental results, the stress-strain relationship is obtained, which result in Young’s modulus and the Poisson’s ratio. In the creep experiment, the time-depending response of polymer film material is studied. The strain state is determined by measuring the deformations over time. Based on the obtained data about the material’s response, the bulk-modulus K(t) is calculated based on BOLTZMANN’s superposition principle.
