Mechanical comparison and Weibull statistical study of different plastic material used in industry

The interest of the present work which is to master mechanical behavior of plastic material to improve and optimize the mechanical characteristics of the three study materials (ABS ,PVC and PR material), another characterization approach was considered in this paper; it is a statistical study of Weibull that allows to have information for the different caracteristics. On the other hand, a Weibull statistical study is carried out to extract the Weibull elements and subsequently define the reliability theory and damage of Weibull. As result of this study, the maximum stress of the studied material of ABS is significantly high, it is also noticed that material have a high specific energy in elastic phase
