The materials were tested under fully reversed constant amplitude loading and under a variable amplitude load history consisting of underloads followed by constant amplitude small cycles.
Fatigue testing was done under fully reversed, constant amplitude bending load.
Ten sheet steel grades have been tested in fully reversed constant strain amplitude loading.
The solution was stirred briskly to dissolve fully in constant temperature bath the temperature of which was 65 °C.
Cyclic stress response at all temperatures was stable under fully reversed constant total strain amplitude (Δε/2) when Δε/2 ⩽ 0.6%.
Fatigue tests were carried out under fully reversed constant amplitude loading (R = −1.0), and fractographic analyses were performed to examine the cracking mechanisms in the exfoliation region.
Though bedsores could not be fully eliminated, constant attendance by a pair of trained professionals kept them to a minimum.
According to the working principles, the CFMs are classified into five kinds of conventional rigid-link constant-force mechanisms and five kinds of fully compliant constant-force mechanisms.
A fully compliant constant-force mechanism that uses an initially angled parallel-guiding mechanism is proposed.
Investigations carried out under fully-reversed, constant amplitude loading with longitudinal stiffeners of the steel grade S700 show impressive fatigue strength improvement far superior to those observed using other mechanical treatments such as hammering or shot peening.
Investigations with longitudinal stiffeners of the steel grade S700 under fully-reversed, constant amplitude loading and under variable amplitude loading with a straight-line spectrum show impressive fatigue strength improvement by high-frequency mechanical impact (HFMI) treatment.
