Unloading pressure reveals how coastal rock fractures under coupled hydro-mechanical stress

Coastal rock doesn't just break under load, it breaks when the pressure is let go. New stepwise unloading experiments show that water pressure and unloading level together weaken rock strength, increase post-unload deformation, and shift energy behavior from elastic storage toward dissipation. This matters for underground stability. Fracture complexity rises with both factors, and a new hydro-mechanical coupling model explains the process.
