Calculating Factor of Safety Considering Temperature

    • talhaensar



      I conducted thermomechanical analysis by coupling steady state thermal and static structural analyses modules. I would like to calculate the factor of safety according to UTS and Sy. But, I would like to consider the temperature effect to FOS. So, I tought that a way as mentioned below;

      1) Determination of UTS (T) and Sy (T) equations by using fitted curves to UTS-T and Sy-T diagrams

      2) Defining the UTS and Sy values  for each nodes by using these equations, 

      3) Dividing the nodal UTS and Sy values to Von-Mises stresses

      I will appreciate it if you can provide macro or any method to define FOS for each nodes. 


      Thanks in advance,

      Hi Talha, 

      You can do this via UDR. 

      Please let me know if you are still interested. 

      Best regards,

      Hi Rohith,

      I accomplished it by using UDF as using steps shared before.

      Thanks for your concern.
