| Abstract [eng] |
The paper is devoted to the problem of stress measurements in polymeric films with Braille and tactile relief elements by using the method of photo-elasticity. A separate Braille and tactile relief element is analyzed numerically by using an axisymmetric model and the problem of determination of distribution of equivalent stress is investigated. Nodal stresses are calculated by using the procedure of conjugate approximation. Equivalent stresses are represented by intensity of the image. A special experimental setup was developed for the measurement of stresses in polymeric materials. The obtained results of investigations are used in the process of design of polymeric films with Braille and tactile relief elements by taking into account the stress distributions in them. |
