Dynamic Mechanical Analysis on Elastomers – Analysis of Viscoelastic Behavior with the LTM

Dynamic mechanical analysis (DMA) on a linear motor testing machine can be used to determine the viscoelastic behavior of elastomers. The load can vary in frequency, temperature and amplitude. These sweeps can be easily defined in the testXpert Research test program. The test software can determine the following results from the resulting strain and stress values: • Loss factor tan δ • E* dynamic modulus • E' storage modulus • E'' loss modulus • Available energy • Energy loss • k* dynamic stiffness • k' elastic stiffness • k'' viscose stiffness These parameters provide information about the viscoelastic behavior of the material. The results of the DMA help to evaluate the fatigue resistance and service life of elastomers under dynamic conditions. 00:06 - Approaching preload 00:18 - Elastomer testing with frequency sweep to determine the viscoelastic properties 00:39 - Outro Dynamic Mechanical Analysis on Elastomers – Analysis of Viscoelastic Behavior with the LTM
