Stress and Strain Analysis of the Traditional Boat Jaloe Kayoh Made of Composite Materials with Centered Loading Using the Finite Element Method

A composite material is a combination of two or more different materials between resin and fiber. The characteristic of this material is that it has a high level of corrosion resistance. This study aims to analyze the strength and durability of Jaloe Kayoh made of jute fiber polyester composite materials. Static analysis on Jaloe Kayoh is carried out through simulation or modeling using CAE-based software with the Finite Element Method (FEM), in static-general conditions. The parameters studied include the stress and strain values for centralized loading on the body of the boat with a minimum load of 650 N and a maximum load of 1950 N. The variations of the materials applied to Jaloe Kayoh include jute, jute-glass, jute-glass-jute, and fiberglass. From the simulation results on the 1950 N loading, the maximum stress is obtained by the jute-glass material with a value of 3.356 × 109 Pa. The greatest maximum strain by jute-glass material is with a value of 1.442 × 10−1. The results of this study show that the four composite materials are categorized as good to be applied as the main material of the Jaloe Kayoh.
