In the safe life method, the S-N curve is used to design a component in such a way that it will not fail within a pre-determined number of cycles.This method differs from safe life in that fail safe assumes that a component will fail, and therefore the component is designed to fail in a safe manner.
What is the concept of fail safe?
A fail safe system is one which, due to the characteristics of its equipment and components and the way in which they are integrated, is guaranteed that, in the event of any fault appearing, the system will always go to a safe status, normally affecting availability but never, and in no case, affecting safety.

In safe-life design, products are intended to be removed from service at a specific design life. Safe-life is particularly relevant to simple metal aircraft, where airframe components are subjected to alternating loads over the lifetime of the aircraft which makes them susceptible to metal fatigue.

Damage tolerance is a property of a structure relating to its ability to sustain defects safely until repair can be effected. The approach to engineering design to account for damage tolerance is based on the assumption that flaws can exist in any structure and such flaws propagate with usage.
