Compression Tests on Surrogate Bone Materials Essay

Compression Tests on Surrogate Bone Materials - Essay Example The core objectives of undertaking this experiment is to compare both high and low densities of bone water when subjected to strain rate of 5, 10, 50, and 100 percent. Through the use of wet or dry bone materials, this experiment will attempt to determine the quantitative differences between elastic modulus of both the wet and dry forms at the different rates of strain. The experiment will also compare experimental and statistical analyses. Finally, the experiment will aim at creating a spring dashpot model for the simulation of the experiment. The test will show that higher elastic modulus will result provided that higher density bone wet foam and dry foams are used. Additionally the experiment will show that strain rate increase results correspondingly increase stiffness while at the same time the material shows viscoelastic tendencies. During the test preparation stage of the experiment in which the creation of mathematical model, formulate the compressed block-equilibrium with the application of FBD. The dimensions of each block were measured, rate of strain calculated, soaking samples in water for the wet form, and calculation of displacement measures. The testing protocol applied in the collection of data included the placement of each sample on the MTS. Time-based intervals were taken into account in applying various rates of strain to each sample. Finally, each sample was subjected to varying rates of strain per second. Among the applied rates included 5, 10, 50, and 100 percent. According to the output table of the experiment, dimensions were taken into consideration that differed from one material to another. However, despite the almost identical dimensions for height, width, and length, it is shown that the dimensional differences are reflected on the results. For the strain rates applied, the results in displacement show that under 100% rate, the displacement was equal to the block height in all cases.
