Target Outcome

Coefficients of a desired constitutive model fitting tissue stress-strain response

Prerequisites

Infrastructure

Python. Python is a programming language (GPL compatible license, http://www.python.org/). Python is the default scripting environment for Open Knee(s); for more details, please refer to Infrastructure/ScriptingEnvironment.
SciPy. SciPy is a Python based open-source software for mathematics, science, and engineering (BSD license, see http://www.scipy.org/).
Spyder. Spyder is an interactive development environment for Python with advanced editing, interactive testing, debugging and introspection features (MIT license, see http://code.google.com/p/spyderlib/).
npTDMS. npTDMS is Cross-platform, NumPy based module for reading TDMS files produced by LabVIEW. TDMS files are the binary files used for the robotic testing raw data. (LGPL license, see https://pypi.python.org/pypi/npTDMS/).

Protocols

Input

Sample tissue geometric properties; width, height, thickness OR diameter, thickness
Sample tissue time-displacement, time-force profiles for multistep stress-relaxation tests
Sample tissue image data (with time stamp) (to reconstruct local tissue strains)

Procedures

Output

Fit to tissue-specific stress-strain data for a desired constitutive relationship
- Constitutive relationship formulation
- Numerical values of coefficients of the constitutive relationship
- Fit error representing the quality of tissue-specific representation of material properties
