Fatigue Behavior Of Continuous Fiber-Reinforced Composite Beams
<p>A study has been taken to evaluate the fatigue behavior of glass fiber-reinforced composite beams. Due to their highly anisotropic properties, composite beams have different failure modes at different stages of fatigue life. The results of the four-point bending fatigue tests show that the …

The corrosion fatigue behavior of notched 2024-T351 aluminum
Notched tensile tests and notched fatigue tests were performed at room temperature to study the corrosion fatigue behavior of aluminum alloy 2024-T351 in 3% salt solution. Notched characteristics of aluminum alloy 2024-T351 were found to be the same as those of other high strength aluminum alloys. …

Low Cycle Fatigue Behavior of Concrete with Recycled Concrete Aggregates
… subjected to high strain, low cycle compressive fatigue is presented. Using a strain based feedback control loop, concrete cylinders are compressed at 15µε/s to a specified strain then unloaded to zero stress for 10 cycles. After cycling, all samples are loaded to a strain of 0.008. Direct …
