This paper deals with the development of loading protocols appropriate for cyclic testing in regions of low to moderate seismicity in Europe. To serve this goal, cumulative damage demands imposed by a set of 60 ground motion records, representative of a European moderate seismicity region for the 2% probability of exceedance in 50 years seismic hazard level, on a wide variety of SDOF systems ar...

To evaluate their usefulness as chemical indicators of cumulative oxidative damage to proteins, we studied the kinetics and extent of formation of ortho-tyrosine (o-Tyr), dityrosine (DT), and dityrosine-like fluorescence (Ex = 317 nm, Em = 407 nm) in the model proteins RNase and lysozyme exposed to radiolytic and metal-catalyzed (H2O2/Cu2+) oxidation (MCO). Although there were protein-dependent...

Vibration fatigue test and analysis methodology for flip chip solder joint fatigue life assessment have been developed by performing vibration tests with constant G-level and varying G-level input excitation. The linear cumulative damage analysis method (Miner’s rule) predicts non-conservative result for vibration fatigue life of flip chip solder joint. Finite element analysis (FEA) using a glo...
