Kececioglu, Chester and Dodge Method Fatigue Curve Equation
Strength and Mechanics of Materials
The Kececioglu, Chester and Dodge Method Fatigue Curve uses statistical distributional data to enable the design of specified reliabilities directly into mechanical components.
Kececioglu, Chester and Dodge Method Method
| Where: | |
 |
= Amplitude of normal (shear) stress [MPa,psi] |
 |
= Endurance limit at constant strength [MPa,psi] |
 |
= Mean cycle stress [MPa,psi]] |
 |
= Ultimate tensile strength [MPa,psi] |
 |
= Ultimate Shear strength When SUS  .8SU [MPa,psi] |
 |
= Exponent depending on joint strength |
| a | = Recommended a <2.6 ...... 2.75> |
