creep test

creep test

[′krēp ‚test]
(engineering)
Any one of a number of methods of measuring creep, for example, by subjecting a material to a constant stress or deforming it at a constant rate.

Also, general time hardening models are developed for both materials and their constitutive coefficients have been determined using creep test data.
This creep test is conducted over just 300 hours and is not intended to advocate a shorter test than the normal 1,000-hour test.
While traditional methods to evaluate environmental stress crack resistance (ESCR) in pressure pipe materials, such as the Full Notch Creep test, can take months, if not years, to complete, SABIC's development reduces this test time significantly, to just a few days.
The permanent deformation was carried out using dynamic creep test performed by the Universal Materials Testing Apparatus (UMATTA).
In China, the earliest rockfill creep test was completed with stress-controlled triaxial equipment by Shen [6] in 1991, and the exponent creep curve model was the first creep model type.
All of the reported 34 bending creep test series (with 340 specimens), were performed with two-part laminated spruce (Picea abies) specimens according to the European structural adhesive creep test standard EN 15416-3.
Creep test was carried out on a device with four-wheel loading, where it is possible to perform creep test for 5 elements simultaneously (Figure 1).
However, due to limitations of the Bent Strip ESCR method, several alternative ESCR tests have been developed for use in the United States and Europe including Pennsylvania Notch Test (PENT), Full Notch Creep Test (FNCT), cone test and notch pipe test (NPT) [1].
Traditional methods for assessing long-term behaviour in pressure pipes like the Full Notch Creep Test (FNCT) and Notched Pipe Test are measured in months and sometimes years.
