is there any difference between durability analysis and stress analysis? If so what is the difference?
 
Stress analysis = prediction of strength, stiffness, buckling, etc under static loads, and sometimes dynamic loads

Durability analysis = prediction of long term performance, degradation, fatigue resistance, etc due to repeated in-service loads and environments
 
the difference between static strength allowables and fatigue strength allowbales (the allowable cyclic load to achieve the desired life)
