Stress Relaxation Tests for Materials and Structures

ASTM E328

These test methods cover the determination of the time dependence of stress (stress relaxation) in materials and structures under conditions of approximately constant constraint, constant environment, and negligible vibration. In the procedures recommended, the material or structure is initially constrained by externally applied forces, and the change in the external force necessary to maintain this constraint is determined as a function of time.

WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM E328 for Stress Relaxation Tests for Materials and Structures. Contact us to learn more.
