Intense fluid pressures enter cracks in attached bedrock, inducing bending stresses that may result in hydraulic fracture of a block. We consider the dynamic response of an attached rock beam to loading during wave impact. We verify the computational method using a known steady-state solution. We show that fast loading leads to greatest stress in the beam and that the beam oscillates before settling to an equilibrium position. These oscillations can produce large stresses long after the impact time.||Funding Details:||Science Foundation Ireland||Type of material:||Conference Publication||Publisher:||International Conference on Hydrodynamics||Keywords:||Boulders; Coastal erosion; Hydraulic fracture; Wave impact; Coastal Irish waters; Aran Islands||Other versions:||http://ichd-home.com/ICHD2018.html||Language:||en||Status of Item:||Not peer reviewed||Conference Details:||The 13th International Conference on Hydrodynamics, Incheon, South Korea, 2-6 September 2018|
