Structural Integrity Assessment of Engineering Components Under Cyclic Contact, 1st ed. 2020 Structural Integrity Series, Vol. 9

This book focuses on surface layers fracture of cyclical contacting bodies (machine parts). Calculation models and calculating procedures of stress-strain states of cyclically contacting solids with cracks, are included. Recommendations for the optimization of operating parameters of joints (contact stresses magnitude, friction/lubrication conditions, materials crack resistance etc) for elements of rolling pairs (wheel?rail systems, backup roll ? working roll of rolling mills etc.) and some fretting pairs are formulated.

Preface.- Chapter 1. Methods of tribojoint elements contact lifetime estimation. A review.- Chapter 2. Calculation model for estimation of cyclic contact lifetime of body with cracks.- Chapter 3. Singular integral equations for some contact problems of elasticity theory for bodies with cracks.- Chapter 4. Rolling contact fatigue. Contact fatigue damages and paths of crack growth in rolling bodies contact zone and estimation of their lifetime by damages formation criteria.-  Chapter 5. Fretting fatigue fracture.- References.
