Text of Abstract
The mechanical properties of human blood are an underdeveloped area of study, yet with proper analysis, the mechanical properties of blood could be used for clinical diagnoses. Using the unique transient rheological signature of a blood sample, there is a possibility that blood rheology measurements could be used as a method of diagnosis and/or differentiation. Rather than focusing solely on traditional transient experiments such as Large Amplitude Oscillatory Shear (LAOS) hysteresis curves are utilized to depict blood flow. The results of these tests are visualized by blood “mechanical contours” that have the advantage of depicting the evolving mechanical properties of the material over a wide range of flow conditions. Rather than solely using the traditional discrete Fourier transform to analyze the hysteresis curve data, a more recent method, Sequence of Physical Processes (SPP), is applied to these transient tests.
