  • measure mechanical properties of cartilage


    We would like to measure mechanical properties of cartilage tissues, both
    statically and dynamically. We would like to be able to do experimental
    testing such as tension, compression, shearing, creep, stress relaxation,

    Some specifications that we are looking for are as follows:
    Modulus Range 0.1 - 100 MPa
    Frequency Range up to 100-200 Hz
    High force resolution
    High displacement resolution
    Tissues can be tested in solution
    Indenter tip size ~ 1 to 3 mm in diameter

    In addition, we would also like to treat the tissue to cause some minor
    'damages' at a later stage. I realize this type of experiments would
    require the machine to possess much larger forces and to be more robust
    (for long treatment times). It would be a bonus if the machine can also do
    this type of experiments. But I can live without it.

    Some machines that we are currently considering include:
    Endura ( ELF 3200 Series)
    Rheometric Scientific (DMTA V)
    TA Instruments (DMA 2980)
    Netzsch (DMA 242)
    MIT (858 Mini Bionix II Test System)

    If any one has used any of these machines, has some comment or advice to
    these experiments, or would like to suggest other machine, a response
    would be highly appreciated.
