Description: An automated way of evaluating the recovery process of polymers was developed. Poly(acrylonitrile butadiene styrene) (ABS) specimens were exposed to a constant strain for 24 hr, and thus stress relaxation occurred. Manual and automated procedures were developed and tested, and the results were compared. The automated data acquisition process was superior both quantitatively and qualitatively in terms of data compared to the manual acquisition. A Weibull distribution function was successfully fitted to the data. The developed experimental setup produced a stable system, reliable data, and it was found that the recovery of ABS followed the Weibull model during the recovery process.
