Abstract

Penelitian ini bertujuan untuk menganalisa dan membandingkan perilaku buckling pillar yang terhubung dengan bracket menggunakan dua metode yang berbeda: pengujian eksperimental dan analisis metode elemen hingga (FEA). Pengujian eksperimental dilakukan dengan uji tekan untuk mengamati deformasi dan beban buckling kritis. Sementara itu, analisis metode elemen hingga dilakukan menggunakan Ansys Workbench Static Structural dan Eigenvalue buckling dengan geometri, kondisi batas, dan parameter pembebanan yang sama. Hasil dari kedua metode tersebut dibandingkan dalam hal Tegangan von-Mises dan Total Deformasi. Perbandingan tersebut menunjukkan bahwa simulasi Finite Element Analysis menghasilkan hasil yang mendekati data eksperimen, dengan persentase perbedaan yang kecil. Hal ini memvalidasi penggunaan metode elemen hingga sebagai metode yang dapat diandalkan untuk memprtediksi perilaku bucking pada komponen struktur kapal dengan jumlah margin tertentu. Hasilnya dapat berguna dalam optimasi desain di masa depan tanpa perlu melakukan pengujian fisik.

This study aims to analyse and compare the buckling behaviour of pillar connected to brackets using two different methods: experimental testing and Finite Element Analysis (FEA). The experimental was conducted using compression setup to observe the deformation and critical buckling load. Meanwhile, the simulation was performed using Ansys Workbench Static Structural and Eigenvalue Buckling with the same geometry, boundary conditions, and loading parameters. The results from both methods were compared in terms of Equivalent (von-Mises) Stress and Total Deformation. The comparison shows that the Finite Element Analysis simulation produces results that are close to the experimental data, with small percentage difference. This validates the use of Finite Element Analysis as a reliable tool to predict buckling behaviour in ship structural components with a certain amount of margin. The results can be useful in future design optimization without the need for physical testing.
