Numerical Analysis of the Perforated Steel Sheets Under Uni-Axial Tensile Force

Abstract

The perforated steel sheets have many uses, so they should be studied under the influence of the uniaxial tensile load. The presence of these holes in the steel sheets certainly affects the mechanical properties. This paper aims at studying the behavior of the stress-strain engineering relationships of the perforated steel sheets. To achieve this, the three-dimensional finite element (FE) model is mainly designed to investigate the effect of this condition. Experimental tests were carried out on solid specimens to be used in the test of model accuracy of the FE simulation. Simulation testing shows that the FE modeling revealed the ability to calculate the stress-strain engineering relationships of perforated steel sheets. It can be concluded that the effect of a perforated rhombus shape is greater than the others, and perforated square shape has no effect on the stress-strain engineering relationships. The efficiency of the perforated staggered or linearly distribution shapes with the actual net area on the applied loads has the opposite effect, as it reduces the load capacity for all types of perforated shapes. Despite the decrease in load capacity, it improves the properties of the steel sheets.

Air Permeability, Shock Absorption Ability, and Flexural Strength of 3D-Printed Perforated ABS Polymer Sheets with 3D-Knitted Fabric Cushioning for Sports Face Guard Applications

“…Therefore, for a given open area, the strength of a perforated sample can be optimized by decreasing the radius of the holes and increasing their number. This can be applicable in estimating the radius of the holes and the bending strength of the core material in the results of this study [ 47 ]. According to the concept of equivalent solid material for design analyses of perforated materials, the equivalent strength of the perforated material is used in place of the strength of the solid material.…”

Numerical and Experimental Investigation of Oil Palm Shell Reinforced Rubber Composites

“…This is because, the effective area that resists the tensile force gets reduced with increasing OPS content. This can be correlated to perforations induced in steel plate, which are likely to reduce the force transmitted [38]. The presence of OPS in rubber matrix reduces the tensile force transmitted in similar manner, since they can disperse only compressive loads and cannot transfer any tensile force.…”

Numerical Analysis of Single-Angle Steel Member Under Tension Force with Different End Deformations

“…The present study aimed to investigate the behaviour of equal and unequal single-angle steel members using finite element (FE) simulations and analysis, which are currently widely used to analyze steel structural elements and have been shown to give highly accurate results [20][21][22]. The single angles are connected through one leg by welding connections under different end deformations, where the deformation is controlled in the two directions perpendicular to the load axis.…”

“…The engineering stress-strain relationship and elastic modulus of the steel elements, which are measured experimentally by tension tests, are acquired from a previously published work [7]. The average engineering stress-strain relationship of the tension test results [7] is applied to FE modeling, as shown in Table 1, with elastic modulus is set to 203 GPa, and a Poisson's ratio of 0.3 is applied [20][21][22]. The model is divided into small elements with l×w×h of 10 ×5 ×5 mm as a maximum size.…”
