Abaqus Stress Relaxation (*VISCOELASTIC, TIME=RELAXATION)
Test ID
G-740
Description
This model is used in ABAQUS as an option of the *VISCOELASTIC model (TIME=RELAXATION TEST DATA). The TestPak includes measurements of relaxation moduli with time over a range of temperatures. Data are fit to a Prony series.
Included Tests
| 1x | M-611 | Stress Relaxation/Creep Compliance by Time Sweeps |
Options
This test is performed for simulation performed in the time domain, for frequency based measurements, please see [G-742].
Samples
: 2 torsional DMA specimen
[details]Application
Data are used in structural analysis simulations to calculate the relaxation of parts with time. This material model must be used in conjunction with *ELASTIC or *HYPERELASTIC. Additional TestPaks may be needed.
