Mechanical Characterization and Failure Analysis of ABS Material Submitted to Static Tests under the Effect of Temperature

Abstract:

In this work, we study the influence of temperature on the mechanical behavior of an amorphous polymer, acrylonitrile butadiene styrene "ABS", based on a series of uniaxial tensile tests on smooth specimens at different temperatures.The results obtained show that the failure of the studied material (ABS) depends strongly on the temperature. Indeed, two zones have been identified: industrial zone T<Tg and thermoforming zone T>Tg (Tg is the glass transition temperature of ABS material).In the industrial zone, we conducted a study of the experimental and theoretical damage via the model of the unified theory. The comparison showed a good agreement concerning the acceleration of the damage process as the temperature increases. In the thermoforming zone, we adopted the same methods to follow the process of flow as a function of the temperature increase. Likewise, we compared theoretical and experimental values which in turn showed a good match. Different stages have been determined in each separate zone, that allows to predict the moment of the critical damage or flow and therefore to intervene in time for a predictive maintenance.
