Fatigue criteria for different materials
Fatigue criteria for different materials
(OP)
Hi,
Are certain fatigue criteria more relevant for certain type of materials? I heard that Gerber is good for ductile materials, etc. So can we use criterion based on material? Any particular reference on this?
Thank you
Geoff

For steels and metals in general, the best fatigue criteria are classified in this sequence:
1) Walker model
2) Morrow model
3) SWT model (Smith–Watson–Topper model)
For Aluminium and titanium alloys, the best fatigue criteria are classified in this sequence:
1) Walker model
2) SWT model
3) Morrow model
