  Hi,
  I calculated the life and damage in nCode DesignLife, and there is damage result for every node.
  Total accumulated damage = 0.00027
  From Miner's Rule 1/0.00027 = 3703, so
  I have 4 hours of data which is acceleration-time, and 3703*4 = 14812 hours life
  This calculating true or not?

  DesignLife is reporting 0.00027 damage produced by the applied loading, which is equivalent to 3703 repeats of the applied loading. If the applied loading represents 4 hours of operation, then the predicted fatigue life is 3703 repeats per 4 hours of operation, which can be converted into 4*3703 per hour of operation.
