This study analyzes the structural strength of a semi-ladder frame chassis by comparing AISI 1018 and AISI 1020 steel using Finite Element Analysis (FEA) on SolidWorks through incremental loading from 1,000 to 5,000 kgf. At peak operational load (2,000 kgf), both materials produced an identical maximum displacement of 0.8475 mm at the Side Body Support Rail (below the allowable limit of 2.655 mm). The highest Von Mises stress was concentrated at the rear kick-up curvature section due to the notch effect, measuring 149.0 MPa (AISI 1018) and 148.8 MPa (AISI 1020), respectively. The chassis remains in the safe region under 1,000–2,000 kgf loads (Factor of Safety / FoS ≥ 1.5), enters a critical condition at 3,000 kgf, and undergoes plastic deformation starting from 4,000 kgf (FoS < 1.0). AISI 1018 steel was selected as the best material because its higher intrinsic yield strength (370.0 MPa vs 351.6 MPa) yields a superior minimum FoS (2.484 vs 2.362). This extra 5.17% safety margin is crucial for ensuring chassis reliability against dynamic shock loads on roads.
