DMA- Tensile/Compressive Mastercurve


Test ID

M-600t

Description

The test specimen is subjected to a tensile or compressive loading over a range of frequencies at a small strain, and the force transmitted through the specimen is measured. E¹, E², and Tan delta are calculated. The test is repeated over a range of temperatures. From this collection of frequency sweeps performed at multiple temperatures, a mastercurve is generated using temperature-time superposition techniques. 

Options

The test can be conducted at different preloads in tension or compression. The oscillatory strain is typically small. Large preloads can result in the non-linear visco-elastic behaviors. This data can also be transformed into relaxation modulus and creep

Standards

  • ASTM D5026

Data

Modulus v. Frequency, Relexation v. Time Mastercurve, aT v. Temperature. This data appears in Matereality as Dynamic Mechanical Properties in Tension.

Replicates

Number of times this test is repeated: 1

Samples

5 flex bars [details]

Application

Through superpositioning, it is possible to test over a small range of frequencies and generate a mastercuve that encompasses frequencies not possible through standard testing. The mastercurve is useful for examining material behavior at very high or very low frequencies.
