Creep Stress Relaxation Tester

Creep Stress Relaxation Tester
A specialized testing instrument designed to evaluate two critical mechanical behaviors of materials: creep and stress relaxation. Creep refers to the gradual deformation of a material under constant load over time, while stress relaxation is the decrease in stress within a material under constant deformation. This machine measures these properties to assess long-term durability and stability—essential for materials used in applications requiring sustained performance under load.

 

Equipped with precision load cells, temperature-controlled chambers (to simulate environmental conditions), and advanced data logging systems, the tester operates in two modes:

 

  • Creep Testing: Applies a constant load to a sample and measures deformation over extended periods (hours, days, or weeks) to determine creep rate and rupture time.
  • Stress Relaxation Testing: Maintains a constant deformation in the sample and records the reduction in stress over time, indicating how materials “relax” under sustained strain.

 

Ideal for materials such as:

 

  • Polymers & Plastics: Pipes, gaskets, and structural plastic components (e.g., automotive or construction parts).
  • Metals & Alloys: High-temperature components in aerospace, power generation, or industrial machinery.
  • Rubber & Elastomers: Seals, O-rings, and flexible parts requiring long-term elasticity under load.
  • Composites: Structural materials in aerospace and civil engineering where long-term stability is critical.

 

Compliant with international standards like ASTM D2990 (polymers), ISO 899-1 (metals), and ASTM E328 (stress relaxation), this tester is trusted by manufacturers, R&D labs, and material scientists. It provides critical data to predict material performance over time, optimize designs for long-term use, and ensure compliance with industry standards for safety and reliability.
