Dynamic Mechanical Analysis: Three-Point-Bending, Cantilever, Solid Rectangular Fixture

In order to cover the demands of dynamic mechanical analysis (DMA) in bending, tension, and torsion, different optimized measuring systems are available for MCR 702 MultiDrive in combination with the linear drive. Due to the material selection and their specific design the measuring systems guarantee precise results and easy handling. The QuickConnect functionality allows one-handed connection of the measuring systems and ensures fast, convenient system changes without the use of a screwing mechanism. Toolmaster™ is the completely contact-free automatic tool recognition and configuration system for measuring systems. Included temperature sensors ensure the highest reproducibility over the entire temperature range without manual positioning of the sensor.

Key Features

Three-point-bending

  • Suitable for dynamic mechanical analysis (DMA) in bending mode
  • Sample is positioned on both ends on a movable sample support while a static bending tool is placed at the midpoint of the sample
  • Measuring errors due to restraints are minimized as no additional clamping of the sample is necessary
  • Suitable for characterizing stiff materials such as composites and thermoplastics below their Tg, thermosets and also metals and ceramics

Cantilevers

Dual cantilever

  • Suitable for dynamic mechanical analysis (DMA) in bending mode
  • Sample is fixed between two fixtures on both ends and on a central fixture at the midpoint of the sample
  • Suitable for materials with low stiffness but also materials which show dramatic changes in dynamic mechanical properties and which could otherwise show strong bowing under load due to the clamping the geometry

Single cantilever

  • Suitable for dynamic mechanical analysis (DMA) in bending mode
  • Sample is fixed between the central fixture and only one fixture at the end
  • Suitable for the characterization of materials which could show strong bowing under load

Solid Rectangular Fixture

  • Suitable for dynamic mechanical analysis (DMA) in tension and torsion
  • Sample is positioned vertically, fixed at the upper and lower fixtures
  • The special design ensures that samples of different thicknesses can be measured exactly aligned with the axis of the measuring system
  • Reproducible results for film, fibers, and also thin solids
  • Suitable for measuring the thermal expansion of solid bars
