Incremental Strain

A rigid-plastic analysis of the axisymmetric deep-drawing problem is made using a special numerical technique. The effects of work-hardening, friction, and normal anisotropy have been included. Incremental strain theory is used to obtain results for both bending and membrane shell theories. These results are then compared. The authors feel that membrane theory gives very good results and should be used in the future to analyze any relatively thin cups.

Stress And Strain Distribution

In the process of the deep drawing of a cup, anisotropy and work-hardening characteristics of the material were introduced, by use of the incremental strain theory, into the calculation of stress and strain distributions and the punch force, and the effect of these characteristics on the limiting drawing ratio was obtained. Calculations were carried out by using the FORTRAN language on an IBM 7094 computer at the University of California.

Abstract Allegheny Ludlum Type 305 (S30500) stainless steel is used for applications requiring a low rate of work hardening during severe cold-forming operations such as deep drawing. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties. It also includes information on high temperature performance and corrosion resistance as well as heat treating and joining. Filing Code: SS-840. Producer or source: Allegheny Ludlum Corporation.

Logical Extension

The present work is introduced and is shown to be a logical extension of work by Chung and Swift, Ray and Berry, et al. The authors introduce the deep drawing process and analyze the stresses due to radial drawing (including friction), bending the sheet, unbending the sheet, and die profile friction. From these stresses, an expression for the total punch load is developed. The authors also describe the experimental work in which determinations are made of the work hardening exponents, the anisotropic coefficients, the friction coefficients, and the total punch load. The paper concludes by comparing the numerical evaluation of the maximum punch load with that determined from experiments.
