Where dudx, dvdx, dudy and dvdy are components of the displacement gradient tensor

 

Tissue sample dimensions:

Thickness: 2.2022 [mm]

Length: 8.94 [mm]

Width: 8.60 [mm]

 

Given the planar biaxial data, based on the tissue dimensions and displacement gradient, 

1. Compute and plot the deformation gradient F as a function of time. 

2. Decompose F into R and U and plot each tensor as a function of time. 

3. Compute the Green strain tensor and plot as function of time. 

4. Plot E11 vs. E22. 5. Compute and plot the 1st Piola-Kirchhoff stress tensor as a function of time. 

6. Plot the normal stress as a function of normal strain relations (1st PK stress and Green strain).

You are welcome to plot the normal and shear components in two different graphs. 

 

How do I set up the MATLAB for this?
