Stucture for cross beams for Catamaran is play a critical role for insured the hull horizontal durability. In normal condition design and calculate, the designer depend on many the approximate empirical formula, the design standard instruction or State Standards. Globalization today, along with the strong development of science, technology and science and technology with the aid of a computer many Complex structural is optimized, it can help the ship can carry more people more load, reduce the weight of the light craft and improve the speed.
Scientific Working Group would recommend calculate and analyze for 2 kinds of materials is Metallic materials like (steel and Aluminium) and Non-metallic materials (FRP composite). With the calculate progress is use the ANSYS APDL for 3D model experienced proof ; Analyze all the load are effect in cross beam (follow rule QCVN 72:2015 MINISTRY OF TRANSPORT); Analyze the structur follow FEA by ANSYS APDL; Optimize the structure follow the cross section by MATLAB)

Analyze the structure follow a finite element model by ANSYS APDL

MATLAB program by Optimization algorithms based on fmincon function
