Elastoplastic behavior strongly controls hydraulic fracture initiation and growth in hydrate-bearing sediments, with plastic strain raising initiation pressure and reshaping fracture geometry. #openaccess at https://www.sciencedirect.com/science/article/pii/S2352854026000306

Shaped cutters outperform conventional designs in hard limestone: ridge cutters reduce peak force by ~8.7% and MSE by ~34%, enabling faster ROP and more efficient drilling. #openaccess at https://shortlink.uk/1n8uL. #Geomechanics #rockmechanics #basin

A new damage-mechanics geostress model shows how progressive rock damage reshapes wellbore stress and improves leakage prediction in deep formations. #openaccess at https://h7.cl/1i8hM #energy #rockmechanics #Geomechanics #Wellbore #drilling #Permeability

For the first time, scientists observed the ‘hidden swirls’ that affect the flow of sand, rocks and snow https://theconversation.com/for-the-first-time-scientists-observed-the-hidden-swirls-that-affect-the-flow-of-sand-rocks-and-snow-262959 #geomechanics #science #STEM

Geomechanics (Earth sciences 🌍)

Geomechanics is the study of the mechanical state of the Earth's crust and the processes occurring in it under the influence of natural physical factors. It involves the study of the mechanics of soil and rock.
