About this Engineering article
Initiation and Growth of Standing Contact Fatigue Cracks by B. Alfredsson; M. Olsson is a Engineering article available to read on EtoBox.
In the standing contact fatigue test an indenter subjects a case hardened test specimen to a stationary but pulsating contact load. Two crack types appearing in the test specimen are investigated. The ring/cone cracks are surface cracks that circumvent the contact area, whereas the lateral cracks are horizontal sub-surface cracks. The initial crack lengths are determined for both crack types. Actual crack paths from experiments are evaluated numerically. For each crack tip position, stress intensity factors are determined from J 1 and J 2 integrals. The stress intensity ranges are compared to criteria for fatigue crack propagation rate and direction. As the cracks propagate, they orient in the direction with mode II loading close to zero.
It is typically read by researchers, students, and practitioners in Engineering.
