By creep test data in one or two months, creep behavior after some years can be predicted with acceptable accuracy. There are several test methods for evaluating long term properties of materials, including creep test ASTM-D2990, stress relaxation test D2991, hydrostatic test D1598, D2837, and DMA ...

amount of time and expense invested in performing these various tests is justification for the establishment of a standardized test method. This paper begins with a review of the world literature on creep-testing

Creep Test Set-up creep test Specimen with steel fibre concrete after 1600 days. Status June '08 The beams have been pre-cracked and then loaded in a displacement controlled manner as prescribed by most international standards relating to steel fibre concrete.
When reporting creep test results the initial applied stress is used. The effect of constant load and constant stress is shown in Fig. 8.3. Note that in general this effect (dashed line for constant stress) only really manifests itself in the tertiary region, which is beyond the region of interest in ...
During the 50%UTS creep test the temperature was raised above the Tgof PET (70 o C). Since theTgwas traversed, these two strain data sets (80.7 o Cand 91.7 o C) should not be used to determine the creep failure time.
