Initial experimental evaluation of a new polyurethane shape memory polymer (PU-SMP) subjected to uniaxial tension carried out at different strain rates is presented. The stress and strain data were recorded and temperature changes from the SMP specimen surface was determined using fast and sensitive infrared camera. Basing on the mechanical characteristics and their relevant temperature changes, the SMP thermomechanical properties have been studied. Influence of the strain rate on the SMP temperature, its structure and behaviour are discussed. Identification of the PU-SMP parameters for one-dimensional rheological model proposed by Tobushi et. al. will be performed.
