Rotary drilling with roller cone bit is often accompanied by wide fluctuations of the weight on bit (WOB). In certain cases, the WOB periodically reduces to null. It has been postulated that in these cases the drill bit lifts off from the formation s

Flex joints in risers introduce abrupt directional changes along the drillstring. High drillstring stresses and flex joint wear rates are introduced, particularly when the drillstring tension is high. An analysis procedure is presented which finds th

Summary Coiled tubing (CT) drilling is a rapidly growing new technology that has been used for shallow new wells and reentry applications. Averaged over the last 4 years, the number of wells directionally drilled with CT has doubled each year from 3

The application of recovery creep theory to the prediction of cyclic loading and heating response of a specific high temperature alloy is illustrated for four different cyclic shapes. It is shown that a satisfactory approximation to the quasi-steady

Most current knowledge concerning the mechanical behavior of skeletal muscle has been obtained from experiments in which the muscle is impulsively activated (twitch) or maximally activated (tetanus). In living organisms, however, muscle usually funct

An idealization of a cylindrical pressure vessel with end plates fastened by longitudinal bolts is considered. The initial axial preload is restricted to be below the load necessary to begin plastic flow and the bolting is assumed elastic throughout

This paper gives the mechanical response of a simplified model of a trailer when its tow point moves along a certain prescribed path. The type of path considered here is described by a constant forward velocity on which is superimposed a low-velocity

A perturbation procedure is used to find the first effects of elasticity in a lubricating fluid on the performance of the bearing. This is achieved by considering an incompressible Maxwell-type material with a small elastic effect in a continuous sle

A method is set up for the rational design of shrink fits, and it is shown that this type of fit is stronger than that obtained with the force fit. The authors describe and evaluate tests conducted on steel collars and shafts which were selected to g
