| Abstract: | In this report we describe the study of the mechanical behavior of the cylindrical GEM detector to be used as new inner tracker for the Kloe2 experiment. The measurements of the tensile tests, that we did to characterize the mechanical properties of the non conventional materials used for the detector, are accurately described. At the end of the experimental tests, we were able to derive the Elasitcity Modulus values for each material and accurately reconstruct the correspective $\\sigma(\\epsilon)$ curves. These experimental values have been used to perform 3-D simulations (by Ansys code) of the non-linear structural response of the detector under several tensile loads, in order to estimate the entity of the consequently induced strain and stress. One of the main objectives of this work, in fact, consists in the realization of a valuable computational tool that allows to foresee and analyze the mechanical response of the GEM detector to specified loads and boundary conditions. In order to be confident in the reliability of the simulation results, a validation against experimental well-know configurations has been done. The comparison between the finite element code predictions with the experimental results is discussed. |
