WebApr 13, 2024 · Auke Bay contains several small islands and reefs within the 11 square kilometer (km\2\) (4.25 square mile (mi\2\)) embayment. While most of the bay is relatively shallow, reaching depths of 40 to 60 meters (m) (131 to 197 feet (ft)), depths of more than 100 m (328 ft) are found near Coghland Island (see Figure 1-2 in the IHA application). WebSep 23, 2024 · In this paper, a peridynamics-based finite element method (Peri-FEM) is proposed for the quasi-static fracture analysis, which is of the consistent computational framework with the classical finite element method (FEM).
