Low-cycle fatigue tests of zirconium alloys using a dynamic mechanical analyzer

Evaluation of the dispersion of carbon nanotubes in an elastomeric polyurethane and fatigue test

“…A new fatigue test for the PU elastomers and its nanocomposites using a dynamic mechanical analyzer (DMA) was tested in this work. Similar fatigue tests were employed for metals [25] or other polymers such as PTFE and SBR [26,27] , but it is the first time that the fatigue of a PU elastomer nanocomposite was evaluated by DMA.…”

Understanding the fretting corrosion mechanism of zirconium alloy exposed to high temperature high pressure water

“…While for SPS, the value is calculated to be in the range of 7.6 MPa to 38 MPa. Previous research [70,71] show that the fatigue strength of zirconium alloys with similar composition at 350 ℃ is over 100 MPa, which is much higher than the cyclic frictional stress (lower than 40 MPa) calculated. So, cracks cannot be formed in the matrix alloy if the cyclic frictional stress acting on the materials is as calculated.…”

Microstructure and fatigue strength of high-strength Cu–Fe and Cu–V in-situ nanocomposite wires

“…No less than three samples of each composite have been used for each stress level. The test procedure is described in detail in [18].…”

“…Earlier, the DMA was applied successfully for comparative single-point bending tests to analyse the fatigue resistance of orthodontic wires (NiTi and Cu-NiTi) with a rectangular cross-section of $0.46 Â 0.64 mm under loading in a medium of certain composition [17] and thin-walled (0.5-0.7 mm) samples of zirconium alloys [18] as well.…”
