... ABSTRACT: This research investigates the poroelasticity of Indiana Limestone, focusing on how confining and pore pressures affect properties like porosity, permeability, and wave velocities. We analyzed the dynamic and static stiffnesses, highlighting the influence of hydraulic properties...

... comminution begins to occur. Both the rhyolite and tuff do not experience such large spikes in helium flow rate, with the rhyolites fracturing at much lower force and the tuffs compacting instead of fracturing due to their high porosity. Both rhyolite and tuff instead experience a lesser but steady helium...
