Area of Science:

  • Biomechanics
  • Biomaterials Science
  • Medical Engineering

Background:

  • Soft biological tissues (brain, liver, kidney, prostate) are increasingly studied in biomechanics.
  • Interest is driven by advancements in computer-integrated surgery, robotic surgery, and virtual reality.
  • Accurate mechanical testing of these tissues presents significant experimental challenges.

Purpose of the Study:

  • To propose a more reliable method for the mechanical testing of very soft biological tissues.
  • To address the limitations of traditional unconfined compression tests, particularly friction issues.
  • To enable the use of no-slip boundary conditions in data analysis.

Main Methods:

  • A novel testing approach for cylindrical specimens with low aspect ratio.

  • Rigid attachment of specimen faces to stress-strain machine platens (e.g., using surgical glue).
  • Utilizing no-slip boundary conditions for analyzing uniaxial compression results.

    • Main Results:

    • The deformed shape of a compressed cylindrical sample is independent of the constitutive law.
    • Vertical extension in the plane of symmetry is directly proportional to the total height change up to 30% strain.
    • Established relationships between measured height change and strain under no-slip conditions.

    Conclusions:

    • The proposed method offers a more reliable approach to testing soft tissue mechanical properties.
    • The findings simplify the analysis of experimental data, particularly for large strains.
    • This technique is relevant for improving biomechanical testing procedures in surgical and virtual reality applications.
