  Uniaxial tensile tests are performed on a polymethyl methacrylate (PMMA)
grade over a range of temperatures near the glass transition and over two
decades of strain rate. Deformation maps are constructed for Young's modulus,
flow strength, and failure strain as a function of temperature for selected
strain rates. The glassy, glass transition and rubbery regimes are identified,
and constitutive relations are calibrated for the modulus and flow strength
within each regime.
