Environmentally assisted cracking (EAC) is the cracking of a material due to interaction of a susceptible material under tensile stress (applied or residual) in a particular environment, often resulting in brittle fracture of an otherwise ductile material. Environmentally Assisted Cracking can occur under static or dynamic mechanical loading.
Capability – At TTL, we have specialized fixtures for stress corrosion, hydrogen embrittlement and corrosion fatigue testing. Stress corrosion tests can be conducted under constant strain, constant load or slow strain rate conditions in a variety of environments.
Some relevant standards:
Touchstone is committed to providing its customers with quality, reliable test results. That is why we have undertaken the rigorous steps needed to meet and secure the most stringent of test lab accreditations including ISO/IEC 17025, NADCAP 7101 (Materials Test Lab) and NADCAP 7122-I (Non-Metallics Materials Testing).
