Best Answer

Bilinear S-N curve theory is a fatigue life prediction model that considers two different slopes of the stress-life curve to account for the crack initiation and crack propagation phases of fatigue failure. The model assumes that different materials have different fatigue behaviors and can be accurately described by two linear segments. It helps in estimating the number of cycles to failure under alternating stress conditions.
