Discussion
- The target outcome is to determine material behavior for all reference model tissues. The stress-strain curve is the ultimate piece of data that determines the Young's modulus of the tissue.
Evaluating Data and Test Repeatability
Skin
This script pulls the data from the .txt file and arranges it into a data frame along with stress and strain calculations. The data structure is dumped into a pickle file to serialize the data. Next, the plot script takes the data structure and performs an analysis to output values that quantify repeatability among tests and provide a visual representation of all tests. It provides the root mean square error (RMSE) to measure the covariance of the curves from 10% strain to the maximum load on the skin after preconditioning.
