TA Instruments DMA Q800 is a powerful dynamic mechanical analyzer, which can be used to perform cyclic tests for shape memory materials and provide accurate stress and strain control and measurements.

What samples can be measured on a DMA? • Immersion clamp kit offers 3 geometries with temperature control from -10 to 200 °C in the FCO. Tension: Up to 25 mm long, 12.5 mm wide and 1.5 mm thick. Compression: 15 mm in diameter; maximum sample thickness is 10 mm.

Aug 26, 2023 · In this context, this study proposes to evaluate the use of the DMA technique in the thermomechanical characterization of SMA regarding the temperature homogeneity of the sample during DMA tests when increasing heating rates are used.

Dynamic Mechanical Analysis, otherwise known as DMA, is a technique where a small deformation is applied to a sample in a cyclic manner. This allows the materials response to stress, temperature, frequency and other values to be studied.

DMA utilizes a system of clamps for mechanical testing of solid polymeric materials. The polymer test sample must first be trimmed, cut or molded into a shape that will work with the selected clamp type.

DMA is used for measurement of various types of polymer materials using different deformation modes. There are tension, compression, dual cantilever bending, 3-point bending and shear modes, and the most suitable type should be selected depending on the sample shape, modulus and measurement purpose.

Samples and Mounting – Samples are typically rectangles (LxWxT) of approximately 25 mm x 6 mm x 1 mm produced in molds, but additional sizes can be accommodated, depending on clamp types (see table below). Ensure all samples have a uniform thickness with uniform lengths/widths.

In this text, the fundamental principles, the basics of DMA, different measurement modes, and measuring systems will be discussed. What is DMA? In DMA measurements, the viscoelastic material behavior of solid-like samples is analyzed.

A Dynamic Mechanical Analyzer (DMA) measures the mechanical/rheological properties of a material as a function of time, frequency, temperature, stress, and strain.

Dynamic mechanical analysis (abbreviated DMA) is a technique used to study and characterize materials. It is most useful for studying the viscoelastic behavior of polymers. A sinusoidal stress is applied and the strain in the material is measured, allowing …
