Compressive Creep
Test ID
M-251
Description
A creep apparatus is used to apply a specified load (stress) to the sample. Duration of the test is typically 1000 hours (can go longer at client's request, with additional cost based on daily rate). Samples are typically rectangular or cylindrical bars. Specimen is placed between two compression platens and connected to a dial indicator. A constant load is applied to specimen at start of test. Measurements of compressive strain are recorded at specified time intervals, throughout duration of test. Two replicates are performed.
NOTE: Due to the long-term nature of this test it is necessary to speak to a sales associate before placing an order. Because the typical test duration is six weeks, priority and economy pricing are not available unless a shorter test duration is desired.
Options
Duration of the test is typically 1000 hours. Tests can be carried out for longer at client's request, with additional cost based on a daily rate.
Standards

Data
Compressive Strain v. Time. This data appears in Matereality as Compressive Creep.
Replicates
Number of times this test is repeated: 2
Samples
6 compressive creep specimens [details]
Application
This test can be used to find the creep modulus of a sample subjected to long term constant compressive loads. It can also be used on a finished product to determine if the part will fail under the specific conditions of the test. By measuring creep at multiple stress levels, isochronous stress-strain plots can be made.
