“…Negative incident strains exceeding the 50% cavitation correspond to a high probability of cavitation Kenner (2.96,3.09 MPa) [60] for distilled water. The variability of other reported dynamic techniques ranged between 5 and 10% [53,[55][56][57]. Considering the existing dynamic methods presented in the literature, only the Tube-Arrest method by Williams et al [53] visually identified cavitating events.…”

“…This method is described in greater detail in the works of Couzen et al [54], Sedgewick et al [55], and Williams et al [56]. Couzen et al [57] reported tensile strengths of negative 0.912, 0.861, and 1.52 MPa for boiled water, tap-water, and boiled deionized water, respectively. Similarly, Sedgewick [55] reported tensile strengths of negative 0.912, 1.01, 1.17, and 1.47 MPa for tap-water, deionized water, boiled tap-water, and boiled deionized water, respectively.…”

Mild traumatic brain injury associated with blast exposure is an important issue, and cavitation of the cerebrospinal fluid (CSF) has been suggested as a potential injury mechanism; however, physical measurements are required to evaluate cavitation thresholds. Modifications to a Split Hopkinson Pressure Bar (SHPB) apparatus were investigated with the aim to generate localized fluid cavitation and measure the cavitation threshold of fluids. The proposed design incorporated a novel closed cavitation chamber to generate localized cavitation resulting from a reflected compression pulse, which was generated by a spherical steel striker and Polymethyl methacrylate (PMMA) incident bar. A numerical model of the incident bar was developed and validated with 24 independent tests (cross-correlation: 0.970-0.997), and this was extended to a numerical model of the apparatus including the chamber, validated with 27 independent tests (cross-correlation: 0.921) to predict the tensile fluid pressure in the chamber. Tests on distilled water were performed with comparable numerical results for the chamber strain (R 2 : 0.875) and chamber end-wall velocity (R 2 : 0.992). The pressure in the chamber was determined from the model to avoid introducing a nucleation site via a pressure gauge, and was verified with a firstorder approximation showing good agreement (R 2 : 0.892). The 50% probability of cavitation for distilled water was −3.32 MPa ±3%, comparable to values in the literature. This novel apparatus, including a closed confinement chamber integrated with a polymeric SHPB apparatus was able to create localized fluid cavitation with loading comparable to blast exposure. Future studies will include the measurement of CSF cavitation pressure.

“…The onset of cavitation bubbles occurs in aqueous solutions when negative stress exceeds -8 to -14 bar (4-6°C temperature jump) [9,19,201. The threshold depends on the initial number of gas microbubbles and impurities [23]. The negative pressure within the irradiated volume brings the slightly heated medium into a thermodynamically metastable phase, which results in the growth of cavitation bubbles [9].…”

A quest for obtaining the absolute metastable limit of liquids has been attempted by many researchers using various methods. The absolute limit obtained was the case having the maximum nucleation rate with one molecule critical cluster from a nucleation theory based on molecular interactions. In this study, the tensile strengths measured by various techniques were compared to the theoretical absolute metastable limit. The tensile strength of water, measured in microscopic inclusions, is close to the absolute metastable limit of 160 MPa while the tensile strength values measured by the centrifugal and acoustic methods is only about 15% of the absolute metastable limit. It has been found that the tensile strength values depend on the experimental conditions which determine the nucleation rate values. Problems related to predicting the absolute metastable limit by the classical bubble nucleation theory were also discussed.
