A}, month = {Jan}, note = {application/pdf, In this study, fatigue experiments of stress ratio 0.1 were conducted using the bovine-cortical-bone specimen under stress frequency of 0.3 and 20 Hz. It was clarified that the fatigue lives of bovine bone increased with an increase in the stress frequency, however the rate of fatigue crack growth lowered with the stress frequency. By considering the crack growth behavior during the fatigue process, computer simulation of the tensile fatigue process of the bovine bone was conducted to clarify the fatigue mechanism of the bone. The obtained S-N curve from the simulation agrees well with the experimental one, and leads the different fatigue lives with the stress frequency., Article}, pages = {102--108}, title = {微小き裂進展特性を考慮した緻密骨の引張疲労過程のコンピュータシミュレーション : 応力繰返し速度の影響 (<特集>生体材料のバイオエンジニアリング)}, volume = {69}, year = {2003} }
