Abstract
The structural design depends on the knowledge of the efforts acting on the structure and also on the knowledge of the mechanical properties and the behavior of the material that composes it. Polymers have been widely applied in the production of several items, including structural requirements. The mechanical properties of polymers are highly dependent on process parameters and their chemical composition. In addition, some properties of polymers, such as: creep, relaxation and fatigue, are quite expensive to obtain. Due to this factor, there is low availability of this information to the engineer, who needs to design a polymeric component under fatigue. Therefore, the objective of this work is to validate a method to design polypropylene components under fatigue, through material characterization, finite element analysis, fatigue life prediction and real component testing. The results obtained were satisfactory, the failure occurred in the region predicted in the finite element modeling, and the number of cycles was compatible with the estimate.
