Peridynamic Analysis of Offshore Jacket Structures

Peridynamics [1] is a new continuum nonlocal theory which reformulates classical governing equation by replacing spatial derivatives with integrals. The motive behind the derivation of novel theory is to incorporate damage in governing equation, thereby treating crack as an integral part of the body. The present study focuses on validating peridynamic theory by implementing it on the OC4 jacket [15]. The beam formulation in the peridynamic framework is derived by Nguyen et al. [12] with all six degrees of freedom. By considering the jacket as a combination of beams, the static and dynamic response of the jacket under static and dynamic point loads are evaluated and compared with classical results.
