LEFM Applications to Concrete Gravity Dams

open access: yesJournal of Engineering Mechanics, 1997
The evaluation of the safety factor of old dams under higher flood levels in the last few years has been investigated under the assumptions of fracture mechanics. The extensive need for research in this field was recognized by the U.S. Army Corps of Engineers that now requires a fracture mechanics investigation prior to the rehabilitation of cracked ...

Kinetic relations and local energy balance for LEFM from a nonlocal peridynamic model

open access: yesInternational Journal of Fracture, 2020
A simple nonlocal field theory of peridynamic type is applied to model brittle fracture. The kinetic relation for the crack tip velocity given by Linear Elastic Fracture Mechanics (LEFM) is recovered directly from the nonlocal dynamics, this is seen both
