Hi Kaushal, 

 

Thanks for your reply. The loads I am applying in the x,y,z directions are the cyclical loading profile of the structure. I currently have my simulation to solve for t=1.5 seconds. The period of the three loads range between 0.3 and 1 second, so I simulated 1.5 seconds in order to capture at least one cycle from each respective load. 

Would this mean my life output would be quoting me cycles of 1.5 seconds? 1e5 * 1.5 seconds lifespan for example? 

The SN curve is not overly applicable to my model given the non-zero mean stress, hence my thinking in using the Goodman correction theory. Have I applied it correctly in the screenshot in my previous message?
