Endurance Limit:
The stress at which a material fractures under a large number of reversal of stress is called endurance limit. It is the maximum stress that a material can sustain for an infinite number of cycles without breaking.
Characteristics of Endurance Limit:
1. It is also known as fatigue limit or fatigue strength.
2. Endurance limit is different for different materials and depends on various factors like load type, surface finish, temperature, etc.
3. It is generally lower than the ultimate strength of the material.
4. Endurance limit is an important parameter in designing components that will be subjected to repeated loading.
5. If the stress applied to a material is below the endurance limit, the material will not fail even if the stress is applied for an infinite number of cycles.
Importance of Endurance Limit:
Endurance limit is an important parameter in designing components that will be subjected to repeated loading. It helps in determining the maximum stress that a material can sustain without failing due to fatigue. This is important in various industries like automotive, aerospace, and manufacturing, where components are subjected to repeated loading. By knowing the endurance limit, engineers can design components that will last for a long time without failing due to fatigue.
