DMA 503 Eplexor® up to 500 N

High force DMA

Highlights

The testing instrument DMA 503 Eplexor® up to ±500 N enables the dynamic mechanical (or static) characterization of a wide range of different materials including elastomers and polymers, composites, metals, glasses, ceramics, biomaterials, foods, adhesives, and liquids.

The modular design of the high force DMA systems allows for measurements in the tension, compression, bending and shearing modes. The testing machines in this series differ from each other mainly in terms of their maximum dynamic force ranges of ±100 N, ±150 N and ±500 N.

Various add-on options make these testing machines a safe investment for the long-term.

Method

The Dynamic Mechanical Thermal Analyzer applies forced periodic loads to the sample and analyzes the phase shift between this primary excitation and the material’s response. The response of an ideal elastic system (e.g., spring) on a sinusoidal load at a given frequency is of the same frequency and exactly in phase with the excitation. The situation changes in a real system: A phase shift (δ > 0°) between the primary excitation and response of the same frequency occurs in the case of linear visco-elastic materials (e.g., polymers).

Elastic and non-elastic properties inherently describe the dynamic mechanical performance of the material. The storage modulus E’, the real part of the Complex ModulusThe complex modulus consists of two components, the storage and the loss moduli. The storage modulus (or Young’s modulus) describes the stiffness and the loss modulus describes the damping (or viscoelastic) behavior of the corresponding sample using the method of Dynamic Mechanical Analysis (DMA). complex modulus E*, represents the elastic component; the Viscous modulusThe complex modulus (viscous component), loss modulus, or G’’, is the “imaginary” part of the samples the overall complex modulus. This viscous component indicates the liquid like, or out of phase, response of the sample being measurement. loss modulus E’’, the dissipated part, is the imaginary part. Depicted in the complex plane, the loss and storage modulus are the projections of the Complex ModulusThe complex modulus consists of two components, the storage and the loss moduli.
