Stress Rupture and Creep Test

Creep testing is a destructive materials testing used to determine the plastic deformation of materials over an extended period of time while subjected to constant stress at a constant temperature. Creep testing is very important for materials required for certain operating temperatures under load, because large strain occurs with the passage of time, and the strain rate is very sensitive to temperature.

Stress rupture testing is used to measure the complete failure time of a material held at a specific load level and temperature.

STEMart provides various stress rupture and creep testing to evaluate the performance of materials with high temperature service applications, such as engines, ovens, and boilers.

Test Capabilities

• High temperature creep testing: Predict the strain trend and fracture life of a material when used for a long time at high temperature.
  • High temperature compression creep testing
  • High temperature tensile creep testing
  • High temperature bending creep testing
  • High temperature torsional creep testing
• Durable strength testing: Determine the endurance strength limit (maximum stress that does not produce fracture at a certain temperature and within a specified time) of a material that do not consider the deformation variables and only consider the service life during high-temperature operation.
• Stress relaxation testing: Determine the initial stress required for the bolted parts to maintain sufficient tightening force during long-term use at high temperatures, and predict the reduction of gasket tightness and spring elasticity.
• Compression creep testing: Determine the increase of compression deformation of materials with time under specified loads.

Test Material Types

• Metals
• Ceramics
• Welding
• Polymers
• Adhesives, etc.
