Elasticity in high water pressure environment

  1. Oct 11, 2006 #1
    How does elasticity change in a high water pressure environment?

    For example, assume you drop a common rubber band in the ocean. As the rubber band sinks, water pressure increases on the rubber band. Excluding any change in temperature of the rubber band, how does the elasticity of the rubber band change as it sinks deeper into the ocean and the water pressure increases?

    Would the increase in water pressure compact the cross-link characteristics of the rubber band, making the rubber band more elastic the deeper it went in the ocean?

    Thanks for your help,

    The elasticity of the rubber band is a constant. The water pressure increases with the depth, but that doesn't make the band alone more elastic. The pressure only increases deformation.
