configuration of exposure time in hyperlife for fatigue analysis.

muhammad ibrahim

i want to know the contribution of exposure time in hyper-life, how should i configure it, considering the sub model of input psd with frf. how does it effect my results, thanks.

Hi,

 

Exposure time is available in HL, as shown below. This means that we're running the event with the PSD during a certain amount of time. Of coarse, as the exposure increases, we expect the damage to increase as well.

You could think o this just like in the lab test. The requirments usually state that the specimen should survive to the PSD excitation for a period of X seconds. That would be the expected exposure time.
