A Corrosion Fatigue/Stress Corrosion Testing Facility at Materials Research Laboratory

Abstract

The mechanical testing facility at Materials Research Laboratory has been employed for conducting corrosion fatigue and stress-corrosion cracking investigations. In this note, attention is focussed on adapting two servo- hydraulic testing machines (MTS) for corrosion fatigue endurance tests on smooth specimens, and the development of an electro-mechanical testing rig for corrosion fatigue crack growth and stress-corrosion cracking tests on notched specimens. Emphasis is placed on specimen design and experimental techniques in conjunction with relatively inexpensive and simple command generation devices. The method of measuring crack growth is reported. Fracture mechanics relations for the determination of crack tip stress-intensity and critical material properties are described. Keywords: Crack propagation, Servo-hydraulic testing machines, Fracture mechanics, Stress corrosion cracking, Electro-mechanical testing machine, Corrosion fatigue, Australia.
