人股骨头关节软骨蠕变性能研究

EXPERIMENTAL STNDY OF CREEP PROPERTIES OF THE JOINT CARTILAGE FOR HUMAN FEMORAL HEAD

为了解人股骨头关节软骨的力学性能，使用日本产ＡＧ－１０ＴＡ电子万能试验机，进行了软骨拉伸蠕变实验。基於蠕变曲线及归一化蠕变曲线基础，建立了蠕变函数及归一化蠕变函数，蠕变函数值与实验值最大相对误差为１１％，能较好的吻合。

To understand mechanics properties of the joint cartilage,we finishedcreep test of the joint cartilagc on the AG-10TA electronic universal experiment machine. Being based on creep ctrves.establish creep function and reduce creep func-tion. Data of the creep function can better tally with test ones.(maximum error 11%)
