Concrete armor units are commonly used to protect shorelines and rubble mound coastal structures. This paper presents the numerical modeling test results for the proposed Hexaloc armor unit under static load. The model shows some value of tensile stress exceeds the critical stress. It was found that the cracking occurred at the top surface of the leg. In the design, the moment due to hydrodynamic and impact loads is not permitted to exceed the cracking moment.
