| Summary: | Synthetic bone substitute has been used for bone implantation in humans. Chemical
composition of this bone substitute is claimed to be close to that of human bone. The
objective of this research is to characterize the response of synthetic bone substitute after
subjected to compressive load. Compression test was carried out on INSTRON Universal
Tester. The maximum load that the specimen can endure and stress-strain response were
obtained from the compression experiment. Qualitative and quantitative characterization was
done using scanning electron microscope and image analyzer. The response of the specimen
showed multiple yield points during compression. Stress-strain response did not follow any
of the response of either ductile or brittle materials. The response was rather strictly nonlinear
throughout the test range undergone. In addition, the mode of failure is more to shear. The
micrographs reveal porosity range, chemical composition and the smallest cell size sustained
after compression. The results of this research can be useful for developing new synthetic
bone or at least improving the properties of the current one. |
