👉 Use strain gage sensors front and back to correct for twist.
In tensile testing, the measurement includes tension, as well as possible bending. Using pair of strain gages allows for the cancellation of bending strains and the measurement of pure tension.
The bonds in any matter holding molecules together are defined by their energy. How much energy (or in our case tensile force) must be added to pull apart these bonds? How much energy is released when this other bond is formed? Bonds are a way of storing potential energy, and every activity involving bonds—making, bending, stretching, breaking and rotating any metallic material —have associated with it a definite amount of energy.
The new CEA-Series (UB) strain gages designed to perform standard compression tests on polymer matrix composite materials. The new sensor patterns feature a unique configuration that is ideal for any strain measurement requiring close proximity to one-sided features, such as weld joints, structural discontinuities or stress risers like holes and cracks.
Structural designers have told us that finding the compression strength of composite materials is necessary and is the subject of ASTM Standard Test Method D6641,The loading device recommended for use in this standard provides a 12.7 mm (0.5 in.) test section length, and a test section width range of 12.7 – 30 mm (0.5 – 1.2 in.), making our new UB pattern geometry ideal for this testing.
The 062UB, 125UB and 250UB patterns are designed with both solder tabs placed on one side of the linear sensing grid, which allows these foil strain sensors to be properly oriented on the composite specimen, keeping the sensing grid centered in the test zone.
Available in 350 ohm to minimize self-heating, the UB patterns are made in the popular CEA-Series construction, which features a thin, flexible, cast polyimide carrier backing and encapsulation, and rugged, copper-coated solder tabs that provides quick and simple soldering. The UB patterns are also available with optional pre-attached lead wires, eliminating the chance of heat damage to the test specimen during soldering.
