Embossment effect analysis on compression of mild steel using finite element methods

Abstract

In the world of construction the use of mild steel is increasing due to the relatively light material and has great strength. This makes the producers start to innovate with the addition of reinforcement to get greater strength. Mild steel is formed from the grinding process on steel plate sheets. Because its thin thickness makes mild steel susceptible to buckling. The use of mild steel as a structural component requires great strength with the addition reinforcement. This research will discuss the effect of embossment width and dimensions on the compressive strength values of mild steel by the finite element method. This thesis uses MIDAS FEA finite element method program. The channel profile used is 75 mm x 34 mm x 5 mm x 0,65 mm with length 2000 mm. Model used is with and without stiffener and embossment distance variation from 15 - 150 mm. Boundary condition used hinge-roller, loading use axial load. The results of the analysis found that the greater the embossment distance, the greater the compressive strength produced. failure that occurs in a stiffener model that has embossment is lateral buckling

Analisis Perubahan Lebar Emboss Terhadap Kekuatan Geser Di Badan Light Lip Channel Menggunakan Midas Fea

“…Acuan emboss berasal dari logam hasil proses cukil yang terdiri atas dua bagian yaitu menonjol dan cekung (Maxipro, 2019). Penelitian tentang terdapatnya emboss pada baja ringan sudah dilakukan untuk menganalisa kuat tekan baja ringan yang menunjukkan bahwa apabila terdapat emboss pada bagian badan sampel akan menambahkan kuat tekan sampel (Darmawan & Leman, 2020).…”
