Vibration fatigue of a vibration fatigue analysis is the modal analysis, that exposes the natural modes and frequencies of the vibrating structure and enables accurate prediction of the local stress responses for the given excitation. Only then, when the stress responses are known, can vibration fatigue be successfully characterized. The more classical approach of fatigue evaluation consists of cycle counting, using the rainflow algorithm and summation by means of the Palmgren-Miner linear damage hypothesis, that appropriately sums the damages of respective cycles. When the time history is not known, because the load is random ("e.g." a car on a rough road or
What Can Be Done at This Point Be Done at This Point". It's also the sixth track on that album. What Can Be Done at This Point What Can Be Done at This Point is the third album by Mexican alternative rock singer, Elan. The album was released in early May 2007. The title track, "What Can Be Done at This Point", is a tribute to the deceased crew of the Space Shuttle Challenger. The track contains audio of the transmission between Challenger and mission control of the day of the tragedy. The track number 6, "Don't Want You in", was the lead single off the album.
