摘要：

The mechanical properties of a thin film of polyurethane shape memory polymer were investigated experimentally. Non-conventional mechanical tests such as nanoindentation, bulging and point membrane deflection are used. The quantitative results obtained by these three experimental investigations are consistent. These tests, performed at room temperature (approx. 35 K below the glass transition temperature T-g) yield a Young's modulus equal to 2.2 +/- 0.4 GPa for the loading sequence and 3.9 +/- 0.3 GPa for the unloading sequence. A weak residual stress has been determined. Moreover, the viscoelastic behavior of the material has been established. (C) 2000 Elsevier Science B.V. All rights reserved.
