Умови сумісної деформації індикатора втомних пошкоджень із замковим з’єднанням бурильних труб

摘要

The conditions of compatible deformation of indicator of fatigue damage and tooljoint are studied. The contact stresses on the surfaces of the coupling parts and the relationshipbetween operational load and size of sliding zone in frictional contact have been defined dependingon the size of the technological gap.
