Special Issue Information

Dear Colleagues,

Advances in materials science have significant roles in the fields of engineering, especially for applications in ocean engineering involving structures and devices with requirements for specific material properties and problems for applications in ocean environments. The oceans have long been recognized as an essential part of the global environment. Covering more than 70 percent of the Earth’s surface, the oceans affect all life on Earth directly as well as indirectly. Ocean engineering is a very challenging field that addresses the use of this vast ocean frontier while striving to protect the same ocean environment and marine life. Materials deterioration and damage caused by interactions with diversified and severe ocean environments point to the need for greater advances in the area of materials science. Advances in the development of novel materials with unprecedented optical, thermal, and mechanical properties would contribute significantly to a wide array of multiple ocean engineering, civil, and defense applications. The aim of this Special Issue is to provide an original and unique environment for researchers in academia and industry to share and discuss their cutting-edge results on novel materials that have potential for use/adoption in the context of harsh ocean environments.

This study conducted numerical investigations on solitary wave attenuation by a vertical plate-type flexible breakwater constructed using hyperelastic neo-Hookean material. The wave attenuation performance and elastic behaviors of the flexible breakwater were discussed systematically by considering the effects of three prominent factors: mass coefficient, stiffness coefficient, and Poisson’s ratio. It is indicated that more compressible and flexible materials are beneficial for enhancing efficiency in mitigating solitary wave energy and protecting the structure from damage. In addition, the performance of the hyperelastic neo-Hookean material model was compared with that of a linear elastic isotropic material model coupled with linear and nonlinear geometry analysis (LGEOM and NLGEOM) by evaluating several key targets: wave reflection coefficient, transmission coefficient, horizontal tip displacement, and wave load. Our findings revealed that the hyperelastic neo-Hookean material model showed almost the same predictions as the linear elastic isotropic material model with NLGEOM, but significantly diverged from that with LGEOM. The linear elastic isotropic material model with LGEOM cannot capture the nonlinear variations in structural geometry and stress–strain relationship, resulting in the underestimation and overestimation of horizontal tip displacement under moderate and extreme wave loads, respectively. Moreover, it underestimates the damage inflicted by solitary waves due to inaccurately predicted wave reflection and transmission. Full article
