Numerical analysis of nanoDMA experiment applied on end plate
Original language description
Hysitron TriboindenterTM TI950 system has been used for studying the viscoelastic properties of bovine intervertebral disc's end plate (EP) by means of nanoscale mechanical dynamic analysis (nanoDMA). NanoDMA offers several testing modes in which is a harmonic function prescribed to the indentation force P(t)=P0sin?t. The resultant displacement amplitude [nm] and phase shift are measured. Then the storage (E') and loss (E'') moduli can be calculated as well as their ratio tan? and complex modulus (E*).These parameters provide the viscoelastic description of our tissue. Sagittally halved bovine spine was obtained from the butchery. Sawed plate of the sample was glued to the bottom of the Petri dish and surrounded by physiological solution with the water free surface. NanoDMA experimental data are supposed to be implemented to the material library of Abaqus and employed to the mathematical simulation of nanoDMA experiment.
