Tensile Creep


Test ID

M-250

Description

A creep apparatus is used to apply a specified load (stress) to the sample. Samples are typically tensile bars. Specimen is clamped between grips at either end, and an extensometer attached. A constant load is applied to specimen at start of test. Strain measurements are made 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

  • ASTM D2990
  • ISO 899-1

Data

Tensile Strain v. Time. This data appears in Matereality as Tensile Creep.

Replicates

Number of times this test is repeated: 2

Samples

6 tensile bars [details]

Application

This test can be used to find the creep modulus of a sample subjected to long term constant tensile 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.
