Abstract

The research intends to produce conventional and intricate shapes using a deep drawing operation experimental work and finite element analysis (FEA). So, to perform experiment work, the dies of deep drawing were designed, manufactured, and then employed to produce the mugs of cylindrical and polygonal shapes from low-carbon steel (1008-AISI). In addition, a commercial software program, ANSYS (workbench), was applied to perform the numerical analysis. The research aim is to create conventional (cylindrical) and intricate (polygonal has eight edges) shapes in a deep drawing process and compare the experimental work results and the FEA of both shapes. The comparison saw that with the intricate shapes, the maximum drawing force demanded to create a polygonal mug registered at 39.865 and 33.675 kN with the cylindrical mug. The maximum effective strain registered was 0.4542 with mugs of intricate shapes. Conventional shapes (cylindrical) are easier than the production of intricate shapes (polygonal has eight edges) by employing the deep drawing operation.

深拉操作下 LCS（1008-AISI）板材常规形状和复杂形状的应力-应变实验和数值分析

该研究旨在利用深拉操作实验工作和有限元分析（FEA）来生产传统和复杂的形状。因此，为了进行实验工作，我们设计、制造了深拉模具，然后用低碳钢（1008-AISI）生产出圆柱形和多边形的杯子。此外，还应用商业软件 ANSYS (workbench) 进行了数值分析。研究目的是在深拉工艺中创建传统形状（圆柱形）和复杂形状（有八个边的多边形），并比较两种形状的实验结果和有限元分析结果。比较结果显示，在复杂形状中，制作多边形马克杯所需的最大拉拔力为 39.865 千牛，而制作圆柱形马克杯所需的最大拉拔力为 33.675 千牛。复杂形状马克杯的最大有效应变为 0.4542。传统形状（圆柱形）比采用拉深操作生产复杂形状（多边形有八个边）更容易。

期刊介绍： Strength of Materials focuses on the strength of materials and structural components subjected to different types of force and thermal loadings, the limiting strength criteria of structures, and the theory of strength of structures. Consideration is given to actual operating conditions, problems of crack resistance and theories of failure, the theory of oscillations of real mechanical systems, and calculations of the stress-strain state of structural components.
