Abstract: This paper presents an original work about the study of stresses for a desmopan membrane by Finite Elements Method (FEM). The desmopan is a thermoplastic polyurethane, so an anisotropic material for which is made in a very wide range of models and types. This requires as input the mechanical characteristics, determined by Digital Image Correlation Method (DICM) and the geometrical characteristics. The stresses, output of FEM, are necessary to calculate the fatigue resistance to limited durability to fracture and after, the reliability studies of membranes. This work forms the basis of reliability studies of the desmopan membranes, that diaphragm pumps are equipped. Determination of fatigue resistance to limited durability for desmopam membrane is very important to estimate the membrane life, respectively, determining the number of failure cycles.
