Low Cycle Fatigue (LCF) and High Cycle Fatigue
(HCF) Tests of Metals
Having the experience of working with Jo Morrow at
the University of Illinois, test system development engineers now
with TestResources have proven themselves with pioneers in metals
Today most LCF, HCF and crack growth tests are performed
for quality audits and the test method is established. We offer standard
test applications software to serve those needs.
Research continues on however, and the work conducted
by the University of Arkansas (Dr. Ashok Saxena) remains on the leading
edge and is performed using several TestResources high temperature
servohydraulic machines by researchers focused on improving and understanding
mechanical behavior of metals at both ambient and high temperatures.
Time-dependent fracture mechanics and low - cycle strain controlled
fatigue experiments continue to contribute to the development of improved
understanding of microstructure-property relationships, reliability
and risk analysis and ultimately how to extend the life of aging structural
A 900LX2 test system was specially optimized
for ambient and high temperature strain controlled low cycle fatigue
(LCF) tests. Special uniquely designed hydraulically operated mechanical
grips maintain the critical alignment and zero-backlash needs for
the test which cycles back and forth from tension into compression
in strain control. Sample insertion takes minutes and can be done
by students without effort. The system includes fatigue test software
that controls the test and analyses results automatically according
to ASTM E606. And with the GDS software platform, researchers can
create their own special applications.
