Experimental and Numerical Stress-Strain Analyses of Conventional and Intricate Shapes of LCS (1008-AISI) Sheet Metal Under Deep Drawing Operation

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.
