Assessment of Systems for Carrying out of Planar Biaxial Tensile Test
Abstract:
Determination of materials behavior subjected to complex stress state corresponding to certain operating conditions is one of the main objectives of material testing. Biaxial and triaxial tests are necessary to facilitate understanding of the materials behavior subjected to complex loadings. Stresses applied in biaxial experiments may constitute the stresses that materials experience during their service life. Test devices attached to the universal testing machine are beginning to be increasingly more widespread due primarily to reduced acquisition, operation and maintenance costs and the possibility to be customized according to specific needs required by type of experiments, to the detriment of freestanding machines. Of these, the most representative devices are pantograph type and sliding type, each having advantages and disadvantages. The present study examines two types of mechanisms that are used to test biaxial cruciform specimens in order to evaluate them in terms of achieving the conditions imposed by planar biaxial tensile testing.
