Effect of various parameters on Wrinkling with imperfections in Deep Drawing of Cylindrical Cup
Due to limitations of finite element methods and software packages, existing in incorporating the imperfections in to the model. The parametric study of BHF, sheet thickness, die profile radius, punch profile radius, initial yield stress and sheet anisotropy and including imperfections is carried out by the model developed by Ravindra.K.Saxena [1, 2, 3]. The mathematical model is studied and va...
متن کاملDetailed experimental and numerical analysis of a cylindrical cup deep drawing: pros and cons of using solid-shell elements
The Swift test was originally proposed as a formability test to reproduce the conditions observed in deep drawing operations. This test consists on forming a cylindrical cup from a circular blank, using a flat bottom cylindrical punch and has been extensively studied using both analytical and numerical methods. This test can also be combined with the Demeri test, which consists in cutting a rin...
متن کاملApplication of Abductive Network and FEM to Predict the Optimal Blank Contour of Elliptic Cylindrical Cup in Deep Drawing
In this paper, the finite element method is employed in conjunction with the abductive network to predict the optimum blank contour of elliptic cylindrical cup with ear-less in deep drawing. The earring behavior of the formed cup is caused primarily by planar anisotropy in the sheet. Different cup heights combined with various aspect ratios of the elliptic cylindrical cup are taken into account...
متن کاملEffect of Die Corner Radius and Punch Corner Radius on Wrinkling and Fracture Limits in Deep Drawing of Cylindrical Cup
Wrinkling and fracture are the important defects in deep drawing operation, which can be prevented using blank holding force (BHF) which has to be optimized as lower BHF promotes wrinkles formation and higher BHF promotes fracturing. Hence the limits of wrinkling and fracture have to be established. These limits depend on various tooling and process parameters. In this work the effect of toolin...
متن کاملWave Propagation in Cylindrical Poroelastic Dry Bones
The wave propagation modeling in cylindrical human long dry bones with cavity is studied. The dynamic behavior of a dry long bones that has been modeled as a piezoelectric hollow cylinder of crystal class 6 is investigated. An analytic solutions for this mechanical wave propagation in a long dry bones have been obtained for the flexural vibrations. The frequency equation for poroelastic bones i...
