摘要

摘要本研究分析了转换场分析的成本效益比，以计算周期穿孔金属板的弹塑性行为。对于不同的网格和有限元阶数，通过实现有限元方法与变换场分析技术相结合来分析精度和计算成本的评估。采用数值研究方法比较了周期穿孔金属板弹塑性分析中变换场分析和标准有限元分析的精度。此外，还利用实验数据对变换场分析结果进行了验证。变换场分析需要采用有限元方法计算应变集中和影响张量。数值结果表明，除了域离散化和有限元阶数的影响外，该技术的性能和良好的场景。

Elastoplastic Analysis of Perforated Metal Sheets using Transformation Field Analysis and Finite Element Method

Abstract This investigation analyzes the cost-benefit ratio of the Transformation Field Analysis to compute the elastoplastic behavior of periodically perforated metal sheets. Evaluation of accuracy and computational cost are analyzed by implementing a finite element approach coupled with the Transformation Field Analysis technique for different meshes and finite element orders. Numerical studies are employed to compare Transformation Field Analysis accuracy with standard Finite Element Analysis for elastoplastic analysis of periodically perforated metal sheets. Additionally, experimental data is employed to validate the Transformation Field Analysis results. The Transformation Field Analysis requires calculating the strain concentration and influencing tensors employing the finite element method. The numerical results show the technique's capabilities and favorable scenarios, besides the influence of domain discretization and finite element order.
