Abstract: Stability is examined with respect to the torque in the elastic element between motor and load in semi-definite systems exhibiting unstable self-excitation during start-up. Equations are provided ...

Abstract: Intersecting bore geometries are used in a number of industrial applications such as in fluid ends of reciprocating pumps. Maximum tensile stresses at stress concentration points in the block ...

Abstract: Published elastic stress concentration factors are shown to underestimate stresses in the root of a shoulder filleted shaft in bending by as much as 21 percent, and in tension by as much as ...

Abstract: Crossbore intersections in liquid ends of positive displacement pumps (PDPs) have regions with high stress concentration. Due to the cyclic loading that occurs in most PDPs, these stress ...

Abstract: The first step in a widely used destructive procedure for measuring through-thickness residual stresses in pipes is a parting-out step in which a coupon is cut from the wall of the pipe. ...

Abstract: A thick-walled cylindrical specimen containing an external circumferential groove was subjected to external pressure. To investigate the maximum pressure sustainable by the reduced wall thickness, ...
