Resumo
The study of membranes behavior when subjected to pressures and tensions from all kinds, as well as their mechanical properties, is receiving a noticeable attention over the last years due to various applications of membranes on various engineering fields, including, actuators, robotics, sensors, airspace, bioengineering and inflatable structures for civil engineering. On this job will be presented a numerical and experimental study of a membrane subjected to an endentation and penetration transversally to the membrane's undeformed plane, considering friction on the interface of the membrane and endentor, which makes this study a pioneer on this kind of analysis. The numerical studies were performed on Abaqus CAE finite element software. The experimental tests are intended to validate the numerical results. Experimental apparatus were developed especially to perform the tests done in this job.
