Attorney, Agent or FirmInternational ClassG06F 015/20AbstractMaterial is periodically indented by a probe driven at an oscillation frency by a shaker regulated by an analyzer to which input measurement data is fed from a sensing head connecting the shaker to the probe for in situ measurement of material resistance to indentation to which such input data relates. A computer connected to the analyzer is programmed to calculate steady-state data on dynamic material properties as a time dependent function, from outputs of the analyzer restricted to limits determined from the input measurement data. | |
