About the Calculus of Fatigue Resistance to Limited Durability for Thermoplastic Polyurethane Membrane
This paper presents an original work about the calculus of fatigue resistance to limited durability for a desmopan membrane, a thermoplastic polyurethane membrane. For this research we needed the values of stresses, determined by Finite Elements Method (FEM). In order to apply FEM, we needed mechanical characteristics of thermoplastic polyurethane membrane, characteristics that have been determined by Digital Image Correlation Method. Mechanical characteristics and geometrical characteristics, with loadings too, are input for FEM soft. The calculus of fatigue resistance to limited durability serves to reliability studies of the thermoplastic polyurethane membranes, that diaphragm pumps are equipped.
