stabilized by the surface energy required to grow these voids. Bubbles in a liquid in tension ($P$) must be larger than a certain critical radius ($R_\mathrm{c}=2\sigma / P$), before it is energetically favorable for them to grow. The vapor pressure inside the bubble has been neglected in the critical radius expression above due to its small contribution compared to $P$, which is on the order of in this work. $R_\mathrm{c}$ corresponds to the radius at which the work of formation of the bubble is maximum ($W_\mathrm{max}$). As was discussed in Section \[introduction\], the cavitation bubbles which grow to relieve tension in the liquid may originate from pre-existing flaws, such as free bubbles or bubbles attached to contaminant particles, but bubbles may also nucleate from random molecular fluctuations in a homogeneous cavitation process. A further consideration in spall experiments is that tension is applied on a timescale which can be comparable to the rate of cavitation bubble growth. This can allow the liquid to remain in a state of tension despite the growth of bubbles if their density or growth rate is insufficient to relieve the tension that is accumulating in the sample. [@Utkin1997; @Utkin2006] The rate of void growth in
