Experimental validation of a flat punch indentation methodology calibrated against unconfined compression tests for determination of soft tissue biomechanics

- Experimental calibration: indentation versus compression of soft viscoelastic gels.
- Simple mathematical indentation models tested for accuracy at large strain (20%).
- We generate correction factors accounting for model errors and specimen geometry.
- Corrected models validated against soft biological tissues; omentum and cartilage.
- Correction factors can be applied to soft materials in the range 0.001-10 MPa.
