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.
