Abstract: An analytical relationship is derived between the strength of a weak stiffness discontinuity and the magnitudes of superharmonic peaks in the Fourier spectrum of a bilinear oscillator. Expressions ...

Abstract: Drill chatter degrades hole roundness, hole size, and tool life. This wastes time and money in tools, scrap, and hole rework. Chatter prediction in milling and turning has shown significant ...

Abstract: Two-dimensional (2-D) strain fields were estimated non-invasively in two simple experimental models of closed-head brain injury. In the first experimental model, shear deformation of a gel was ...

Abstract: Chatter in milling and other interrupted cutting operations occurs at different combinations of speed and depth of cut from chatter in continuous cutting. Prediction of stability in interrupted ...

Abstract: The mechanical characterization of soft anisotropic materials is a fundamental challenge because of difficulties in applying mechanical loads to soft matter and the need to combine information ...
