  • PS0029-417 Evaluation of viscoelastic strain of polymer material during unloading process by digital image correlation method

抄録

To evaluate the effect of non-uniform deformation on the elastic and viscous strain during unloading of the polymeric material, strain distribution after loading, unloading were measured by digital image correlation method. Local viscous strain was obtained by removing the elastic strain from total strain cased during unloading. Obtained results clarified that the strain recover in necked region was very small while those caused in necked surrounding region was large.
