Outline of Final Research Achievements |
Detailed analysis of biaxial stretching properties of visco-plastic polymers such as amorphous polymers around the glass transition temperature or inhomogeneous thermos-plastic polymers was performed by using a newly developed biaxial stretching apparatus combined with a polarizing imaging camera. A new phenomenological strain energy theory introducing dissipative terms for plastic behavior well described the biaxial stretching properties the polymers. The theory also well described with birefringence development during the stretching.
