CREEP AND STRESS RUPTURE

The Mechanical Testing Department at our Portland, OR facility is well equipped to perform Creep and Stress Rupture testing of a wide variety of materials to both standard and customized specifications.   Over 50 test frames are available, covering a broad array of load and temperature ranges. A complete in-house machine shop supports the department with precise specimen preparation and fixture fabrication. For more information on our Creep and Stress Rupture capabilities, please contact:

Doug Puerta (Laboratory Director - OR)

April 2011 -  We are now GE S-400 accredited for Creep testing.  Contact us today for a quote or more information!

TEST METHODS
ASTM E139 Standard Test Methods for Conducting Creep, Creep-Rupture, and Stress-Rupture Tests of Metallic Materials
ASTM E292 Standard Test Methods for Conducting Time-for-Rupture Notch Tension Tests of Materials
   
  • The 20,000 lb. machines are for room temperature testing only and are used for hydrogen embrittlement testing.
  • All specimens are single-point machined (no plunge grinding). 
  • Specimens are typically loaded within 24 hours of receiving the material.
