Random vibration test for electronic assemblies fatigue life estimation

High-cycle fatigue life prediction for Pb-free BGA under random vibration loading

“…Under this assumption, the response stress within the 1-r level, 2-r level, 3-r level results in 68.3%, 95.4%, and 99.7% of the time, respectively, where the r level stresses can be obtained from ANSYS. Since the r level stresses are statistical quantities, the three-band method provides quick but less accurate fatigue life estimation, as shown in the previous work [14], than the methodology applied in this work.…”

Random Vibration Fatigue Analysis of Car Roof Luggage Carrier

“…Most studies applied in vibration situations are constrained to random vibration filling, preferably of typical harmonious excitations. Notwithstanding, a massive division of high-cycle fatigue examination is unaccompanied touched by foretelling electronic components' fatigue life presented to a random vibration (Al-Yafawi et al, 2010). Chen et al, (2008) mixed the vibration breakdown review, FEA, and analytical formularization to determine the electronic parts' fatigue life.…”

“…García et al, (2018) used Steinberg's methodology to estimate the fatigue life of materials utilised in the space application applying FEA. Yet, since the 3σ stresses are statistical models, the 3σ process presents responsive limited reliable fatigue life prediction, as explained in the earlier (Al-Yafawi et al, 2010), than the method utilised in this area.…”
