It not only depends on the load level, but also depends on the frequency or time and the ability to resist the fatigue damage of materials.[2] As the buoy in the ocean to realize periodic floating down, and most of the time are completely immersed in seawater, so the load bearing the main wave current complex alternating load.
It is based on the stress of materials or parts and use Miner linear cumulative damage theory and rain-flow counting method to proceed total life analysis.
The strain - time data recording turned 90 degrees, the time axis vertical downward, data record is like a series of roof, rain along the roof down the stream, the process is called rain flow time course of rain flow counting method for load counting method for counting reflects the memory characteristics of materials, has a clear mechanics concept, so the method has been widely accepted.

However, when considering heat resistant Nickel superalloys used to make gas turbine engine components, gaseous porosity is not taken into consideration as the melt is poured in a vacuum chamber and requirements to the purity of the raw material are very stringent.
Actual value of shrinkage porosity for a wide range of casting materials requires calibration based on the results of actual hardware testing.
Study of temperature profiles in the domain of computation during metal pouring and casting solidification is held by means of a differential equation of energy conservation , (1) , (2) The expression for enthalpy is as follows , (3) , (4) Where indices: 1, 2 and 3 refer to zones V1, V2 and V3 respectively, T – temperature; t – time; ρ – material density; сp – specific heat capacity; L – specific phase change heat capacity; – heat conductivity factors tensor; – efficient melt velocity vector calculated through the true velocity of the liquid phase as follows: ; – relative fraction of liquid phase; – relative fraction
