In addition to rheology, MCR rheometers can also be used for Dynamic Mechanical Analysis (DMA) of solids in torsion. The temperature and mechanical behavior of solids is investigated with a variety of available fixtures such as solid rectangular or circular fixtures (SRF, SCF). The oscillatory signal is measured by the EC drive while the lift drive of the rheometer is used to set a pretension and compensate the thermal expansion. This guarantees a precise determination of the shear moduli G’ and G’’ as well as the loss or damping factor tan(δ), especially in critical regions between glass transition temperature and melting point.
