This paper examines the validity of using the small-punch test technique as a means of quantifying the mechanical properties of acrylic bone cement under different test conditions. The elastic moduli calculated using the small-punch test method were compared with data measured using the international standard for acrylic bone resin, ISO 5833. Conclusions from the study indicate that the small-punch test is a reproducible miniature specimen test method that can be used to characterize the mechanical properties of retrieved acrylic bone cement as used in total joint replacement surgery. Moreover, the test conditions were found to influence the elastic modulus of acrylic bone cement. The test temperature had a greater effect on the elastic behaviour of the bone cement than the test medium.
本文研究了使用小冲头试验技术作为量化不同测试条件下丙烯酸骨水泥力学性能的一种方法的有效性。将使用小冲头试验方法计算得到的弹性模量与采用丙烯酸骨树脂国际标准ISO 5833测量的数据进行了比较。该研究的结论表明,小冲头试验是一种可重复的微型试样试验方法,可用于表征全关节置换手术中取出的丙烯酸骨水泥的力学性能。此外,发现测试条件会影响丙烯酸骨水泥的弹性模量。测试温度对骨水泥弹性行为的影响比测试介质更大。
