... to investigate the full-field strain map and the mechanism of crack development during conventional cutting (CC) and ultrasonically assisted cutting of cortical bone. A novel method for calculating cutting and thrust forces under the mixed fracture mode of bone was also proposed. Extensive experimental results...

...Michael Conward; Johnson Samuel This article aims to investigate the characteristic microstructure-based failure mechanisms observed during the fracture cutting of age-varying bovine cortical bone. To this end, orthogonal cutting experiments are performed on cortical femoral bones harvested from...

... by gradient structures involving varying percentages of osteon, interstitial matrix, lamellar bone, and woven bone. The mean absolute percentage error in the force predictions is under 10% for both the cutting and thrust forces. The reality of spatially varied properties in the cortical bone limits...

...Roshan Mishra; Michael Conward; Johnson Samuel Part 2 of this paper is focused on modeling the acoustic emission (AE) energy rate as a function of the specific cortical bone microstructures (viz., osteon, interstitial matrix, lamellar bone, and woven bone) and the depth-of-cut encountered...
