While calculating the stress-induced in a closed coil helical spring,...
The maximum stress felt near a crack occurs in the area of lowest radius of curvature.A stress concentration factor is the ratio of the highest stress (smax)) to a reference stress (s) of the gross cross-section. As the radius of curvature approaches zero, the maximum stress approaches infinity.

Curvature and Stress Concentration Effect:
Wahl's factor is used to account for the curvature and stress concentration effect in a closed coil helical spring. When a spring is wound into a coil, the wire is bent and twisted, leading to stress concentrations at certain points along the coil. These stress concentrations can weaken the spring and reduce its overall performance. Wahl's factor helps to adjust the calculated stress to account for these effects, ensuring a more accurate estimation of the spring's behavior.
Shock Loading:
While shock loading is a factor that can affect the stress levels in a spring, Wahl's factor is specifically designed to address the curvature and stress concentration effect in a closed coil helical spring. Shock loading may require a different approach or consideration when calculating the stress induced in a spring, but Wahl's factor is not directly related to this type of loading.
Poor Service Conditions:
Poor service conditions, such as exposure to corrosive environments or extreme temperatures, can also impact the performance of a spring. However, Wahl's factor is primarily used to address the curvature and stress concentration effect in closed coil helical springs, rather than factors related to poor service conditions.
Fatigue Loading:
Fatigue loading, which involves repeated or cyclic loading that can lead to failure over time, is another important consideration in spring design. While Wahl's factor does not specifically account for fatigue loading, it does help to ensure that the calculated stress levels in a spring are more accurate by considering the curvature and stress concentration effect. Properly addressing these factors can help to improve the overall durability and reliability of a closed coil helical spring.
