DESCRIPTION:Polycarbonate\, a widely used glassy thermoplastic polymer\, i
 s essential for applications requiring high strain rate performance. Despi
 te its common use\, there are gaps in understanding its performance\, part
 icularly regarding adiabatic heating effects. This research provides compr
 ehensive experimental characterization of polycarbonate\, integrating expe
 rimental and modelling efforts. Key achievements include: (1) a detailed a
 ssessment of quasi-static tensile tests\, incorporating full-field strain 
 and temperature measurements for more accurate material model calibration\
 ; (2) comparative compressive characterization of four polycarbonate mater
 ials under varied strain rates and temperatures\, revealing the interplay 
 of these conditions\; (3) unique measurements of temperature rises during 
 deformation in adiabatic conditions across a range of starting temperature
 s\, quantifying the effect on the Taylor Quinney Coefficient\; and (4) the
  use of thermal and X-ray imaging to understand damage formation in short-
 fiber filled polycarbonate at high strain rates. This research enhances un
 derstanding of polycarbonate materials at high rates\, aiding the developm
 ent of constitutive models over various temperatures and strain rates.
