Mechanical Properties of thighbones of crossbred swine which were fed a normal diet and were about 20^-30-week-old, were determined through the indentation, the parallel plates compression, and the three-point bending tests.Raw specimens which were the tip of thighbones cut out from the whole-bone, were tested in indentation. On the other hand, cylindrically formed specimens which were cut out from the bone stems, were tested in parallel plates compression and three-point bending.Mechanical Properties of swine thighbones are summarized as follows.1) The indentation strength for joint cartilage of thighbone ranged from 20-40 N/mm2.2) The apparent modulus of elasticity for joint cartilage of thighbone was found to be 41-161 N/mm2.3) Test specimens of bone stem which were subjected to parallel plates compression or three-point bending, showed an elastic behavior.4) The compressive strength for bone stem varied from 134-219 N/mm2.5) The bending strength for bone stem was found to be 158-261 N/mm2.6) The modulus of elasticity of bone stem due to bending was about 8400-16600 N/mm2.

通过压痕试验、平行板压缩试验和三点弯曲试验测定20^-30周龄正常饮食的杂交猪大腿骨的力学性能。原始标本为从全骨上切下的大腿骨尖端，进行压痕试验。另一方面，从骨干上切下圆柱形样品，进行平行板压缩和三点弯曲测试。猪大腿骨的力学性能总结如下。1）大腿骨关节软骨的压痕强度范围为20-40 N/mm2。2）大腿骨关节软骨的表观弹性模量为 41-161 N/mm2.3) 骨干的测试样本经过平行板压缩或三点弯曲，表现出弹性行为。4) 骨干的抗压强度变化范围为 134-219 N/mm2.5) 骨干的弯曲强度为 158-261 N/mm2.6) 骨干因弯曲而产生的弹性模量约为 8400-16600 牛/毫米2。
