Title:Temperature dependent bulge test for elastomersAuthor(s):Umut Dogar Cakmak, Imre Kallai, Zoltan MajorAbstract:The bulge test is a particularly convenient testing method for characterizing elastomers under biaxialloading. In addition, it is convenient to utilize this test for validating material models in simulationdue to the heterogeneous strain field induced during inflation. During the bulge test the strain fieldfor elastomers covers uniaxial tension at the border to pure shear and equibiaxial tension at the pole.Elastomeric materials exhibit a hyperelastic material behavior, with a dependency on temperature andloading rate. The temperature effect on the mechanical behavior during biaxial loading is consideredin the present study. A bulge test setup combined with a temperature chamber is developed in order tocharacterize this effect, and an exemplary temperature dependent characterization of a poly(norbornene)elastomer is performed with this setup. The equibiaxial stress–strain curves measured at 60◦C, 20◦C and−20◦C are presented.Journal:Mechanics Research CommunicationsPublisher:ElsevierISSN:1873-3972Page Reference:6 page(s)Publishing:6/2014
