...Martin B. G. Jun; Chanseo Goo; Mohammad Malekian; Simon Park This paper investigates the mechanistic modeling of micro end milling forces, with consideration of the effects of plowing, elastic recovery, effective rake angle, and flank face rubbing. Two different mechanistic models are developed...

...Paul S. Nebosky; Steven R. Schmid; M.-A. Sellés This study examines the elastic recovery (springback) of a porous tantalum foam after sheet forming operations. The foam and sheet-like form is applicable to bone ingrowth surfaces on orthopedic implants and is desirable due to its combination of high...

HFM has been modeled as a long six-layer fiber membrane, and the HFM inner skin layer has been treated as a thin-walled elastic cylindrical shell under the shrinkage-induced inward radial pressure. The groove number has been reasonably estimated based on the resulting buckling mode as compared...
