STRUCTURAL ANALYSES OF THE COMPOSITE MATERIAL FOR AUTONOMOUS MODULAR SYSTEM USED AS LATERAL MARK IN BRACKISH WATER HABITAT
Abstract
The safety of navigation and life in the risk areas adjacent to the coastal area, represent the central objective of the paper and meet the provisions of the European directive "in force." In this context, for defining the geometry of the autonomous modular system used as physical system for marking the fairway, mathematical prediction models were developed. The prediction of phenomena and functional characteristics for autonomous modular system was possible by using a specialized software, where the calculation conditions were for sea state maximum 6 Beaufort scale. The configurations were round geometric bodies generated by the rotation of a triangle around the straight line containing the largest side and two rectangular trapezoids joined at the large base and rotated around the side perpendicular to the bases, and the constraints were initiated on the submerged side of each system. The post-processing enabled the visualization of the results: the deformation, the Von Mises stress fields and the distribution of displacement vectors. The state of tension was calculated, resulting in values that fall within the range -5.96e+006 to 5.85e+007 N/m2, below the allowable strength of the material, so the composite material with textile matrix will resist to the distributed force imposed. Descriptions of the study, main problematic and used methods are discussed.
