Hi everyone
Basic question. PD5500 is being used to carry out a high cycle fatigue analysis of a fillet weld. The weld is subject to a simple sine-wave type loading which puts the weld through simple tension-compression cycles. The stress in the weld is being calculated using simple hand calculations. Would it be correct to assume for a fatigue assessment that the calculated stress range for a single cycle of loading would be (peak stress in tension - peak stress in compression)? Thus the stress in compression adds to the total calculated stress.
Thank you.
