| Summary |
Tensioned membrane structures have so small flexural stiffness that they can not transmit compression stress. The wrinkling of membrane becomes a common problem. The increasing demand for better characterization of materials and components in many cases requires whole- field imformation for the analysis of the mechanical behavior in wrinkling generation process. Electronic speckle pattern interferometry (ESPI) offers the possibility of whole-field and non contact measurement of displacements and strains. In this paper, ESPI is applied to observe a wrinkling generation process of tensile tests of the rectangular membrane structures. It is found from the experimental test results that a wrinkling occurs at an inflection point of the load - minimum principal strain.
