【 摘 要 】

Physical parameters of Braille elements formed on polymeric films including biodegradable ones were tested in the investigation presented in this paper. A separate Braille element is analyzed. Plane strain and axisymmetric problems are investigated. At the places of maximum equivalent stresses deterioration of quality of material of a Braille element is expected. Equivalent stresses are used for determination of the number of cycles till the start of wear at the surfaces of the Braille element when the film performs vibrations according to the eigenmode. Graphical representations are obtained. The results of performed investigations are used in the process of interpretation of measurements of wear of vibrating Braille elements.
