New Frontiers paper on coalescence of microcracks using work optimization

April 26, 2022 – 7:50 pm

Fattaruso, Laura, Michele L. Cooke, Jessica McBeck, 2022. The influence of fracture growth and coalescence on the energy budget leading to failure, Frontiers in Earth Science, doi.org/10.3389/feart.2022.853030

image of 8 plots. the left column shows the stress around the pre-cut faults. The right 6 show the opening and sliding on microcracks with fault evolution.
This plot shows the partitioning of energy between frictional work and internal work for both homogeneous and heterogeneous (with microcrack) models. The heterogeneous model requires greater energy to fail.
