Rapid estimation of ductile crack formation in cross-wedge rolling
This study investigates the problem of predicting material cracking in cross-wedge rolling (CWR). Fifty-four cases were analyzed using the finite element method (FEM), and maximum values of the damage function were determined.

Stability evaluation of rotor/bearing system [PDF]
A stability study of rotor/bearing systems is presented. Even though it was limited to study of a fully lubricated bearing subject to oil whirl, and further limited to low eccentricity region for linearity and with only one type of lubricant, it can be ...
