Energy absorption behaviors of designed metallic square tubes under axial loading: Experiment-based benchmarking and finite element calculation

Abstract

In this article, the load resistance and energy absorptions of thin-walled structures on the square tube were numerically evaluated by the finite element method. This structure can be widely used in automotive industries, industrial buildings, ships, offshore platforms, and airplanes. In the finite element method, thin-walled structures on square tubes were examined with different wall thicknesses and materials. The materials used are mild steel, SAE 1045 steel, and SAE 1008 steel. Using the numerical results, the thickness of the wall influences the strength of the structure. Moreover, SAE 1045 steel material also seems to increase the strength of the tube under axial loading compared to the mild steel and SAE 1008 steel material. It is also important to remember that the finite element solution depends on defining your mesh size and boundary conditions. The mesh size is also compared and assessed.

Forecasting the Effects of Failure Criteria in Assessing Ship Structural Damage Modes

“…The fluctuations in the load are caused by the formation of successive folding events, in which each subsequent peak corresponds to the onset of a folding process. These phenomena on the maximum load and the folding process, which are related to load fluctuation, are also evident in the case of the tube under compressive load as examined by [26,32,33]. For torsion damage, Germanischer Lloyd (GL), Peschmann, Rice-Tracey, and Cockcroft-Latham (RTCL) produce shear stress at approximately the same stress: 460.44, 460.09, and 459.72 MPa, respectively.…”

“…It shows that 2 mm mesh has a similar load vs. displacement curve trend compared to the experimental data. It is revealed that mesh size selection is a crucial aspect in terms of numerical modeling verification [26][27][28][29]. specimen geometries and applied load and boundary conditions are determined as shown in Figure 8.…”

Numerical Analysis of Openings in Stiffeners under Impact Loading: Investigating Structural Response and Failure Behavior

“…The presence of stiffeners in the stiffened plates, which are commonly used in ship structures, had a significant impact on their strength [17]. Maximum force and generated energy are typically used as reference data to assess structural strength in ships [18][19][20].…”

Failure criteria in crashworthiness analysis of ship collision and grounding using FEA: Milestone and development

“…The FEA model simulates the ship's response to impact loads, such as those encountered during a collision, by dividing the ship's structure into smaller, manageable components called finite elements. These elements are then analyzed using mathematical equations to determine their behavior under different loads [7][8][9][10][11][12]. The results of the analysis can be used to evaluate the strength and integrity of the ship's structure and identify potential areas of weakness that may need to be reinforced.…”
