Abstract

This study investigates the influence of stiffeners and their positioning on the bending behavior of thin stainless-steel plates. Three experimental models were employed: a simple un-stiffened plate, a plate with one stiffener and a plate with two cross stiffeners with clamped boundary conditions. Numerical analysis with ABAQUS software and the C3D8IH solid finite element is carried out and the obtained results are compared to those found experimentally. The findings reveal that the introduction of stiffeners significantly enhances the structural rigidity of the plates, leading to reduced displacements under applied loads. Very good efficiency was observed where the accuracy of the numerical model improved with increasing load, particularly for the cross-stiffened configuration. The error rates between the numerical and experimental results decreased from 19.9336% at lower loads to as low as 0.1675% at higher loads, underscoring the effectiveness of stiffeners in minimizing deflection and aligning theoretical predictions with the experimental outcomes. This research provides valuable insights into the design of stiffened plates for applications requiring enhanced load-bearing capacity and reduced deformations.

加强筋结构对不锈钢薄板弯曲性能的影响:实验与数值研究
本文研究了加强筋及其位置对不锈钢薄板弯曲性能的影响。采用三种实验模型:边界条件固定的简单无加筋板、单加筋板和双交叉加筋板。利用ABAQUS软件和C3D8IH实体有限元进行了数值分析,并与实验结果进行了比较。研究结果表明,加强筋的引入显著提高了板的结构刚度,从而减少了在施加载荷下的位移。数值模型的精度随着载荷的增加而提高,特别是对于交叉加筋结构,效率非常高。数值与实验结果之间的错误率从较低荷载下的19.9336%下降到较高荷载下的0.1675%,这表明加强筋在最小化挠度方面的有效性,并使理论预测与实验结果保持一致。这项研究为需要增强承载能力和减少变形的加强型板的设计提供了有价值的见解。

期刊介绍: Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
