Alternate and recurring heat of water through a pipe

      So I am trying to find out what is happening to the pipe's material when cold water passes through the pipe for a few minutes and then hot water for a few minutes. I want this process to repeat a few times and then plug this data into a static study for the pipeline in order to see the fatigue of the pipe. how many lifecycles it has before it is destroyed. 

       

      Thank you in advance,

      Hi,

      When cold water flows through a pipe, the material experiences thermal contraction, causing it to slightly contract. Conversely, when hot water flows through the pipe, thermal expansion occurs, leading to slight expansion of the material. This cyclic thermal stress can induce fatigue in the pipe material over time.

      To assess the fatigue life of a pipe under these conditions, several factors need to be considered, such as the pipe material, its mechanical properties, the pipe's geometry, and the magnitude and frequency of the temperature variations. Additionally, other factors like pressure, flow rate, and environmental conditions may also influence the fatigue life.

      Thank you

      Thank you for your apply.

      I totally understand it, but I want a guidance on how to set the simulation. 
      Do you have a video or something which shows step by step the simulation?

       

      Thank you in advance,

      Hi,

      I have shared fatigue analysis video:
