Pore geometry as a control on rock strength - ScienceDirect

Jan 01, 2017· Pore shape – not just porosity – is an important control on rock strength. Pore shape controls stress perturbation size and distribution during compression. Variable pore shape can account for up to an order of magnitude strength variation. Some void shapes are relatively stable with respect to an applied compression.
