Strength Analysis of Welded Joints on Railway Bogie Side Frame with Welding Current Variations Using the Finite Element Method Ojo Kurdi Achmad Widodo Toni Prahasto Muhammad Rizky Hidayat Volume 3, Issue 5, Pages 1-9, May 2026 The quality of welded joints on railway bogie side frames is a critical factor in ensuring the structural integrity and operational safety of rail vehicles. This study investigates the effect of welding current variations on the mechanical strength of butt-joint welds on SM490 steel, which is widely used in bogie frame fabrication. Welding was performed using the Gas Metal Arc Welding (GMAW) ... Read More Article DOI: doi.org/10.47001/CJESR/2026.305001
Finite Element Analysis of Radial Gate Arm Buckling under Hydrostatic Loading Using One-Way FSI Ojo Kurdi Berkah Fajar TK Dwi Basuki Wibowo Khoiri Rozi Zaki Ahmad Fitriawan Volume 3, Issue 5, Pages 10-16, May 2026 Radial gates are critical hydraulic structures used in spillway systems to regulate water discharge under various operational conditions. The radial arm functions as the primary compression member responsible for transferring hydrostatic loads from the gate leaf toward the trunnion support. Due to its slender structural configuration, the radial arm is vulnerable to instability failure in the... Read More Article DOI: doi.org/10.47001/CJESR/2026.305002
Critical Buckling Load Evaluation of Aluminum Columns Based on a Comparison of Euler Theory, Experimental Testing, and Finite Element Method Toni Prahasto Nazaruddin Sinaga Ojo Kurdi Ismoyo Haryanto Aditya Daffa Pambudi Volume 3, Issue 5, Pages 17-24, May 2026 This study aims to evaluate the Buckling strength of aluminium alloy 2024-T3 columns based on Euler’s theory and to compare the results with numerical simulations using the Finite Element Method (FEM) and experimental testing. The column lengths considered in this study are 400 mm, 450 mm, 500 mm, 550 mm, and 600 mm, with a constant cross-sectional dimension. The analysis is conducted for t...
