Analysis of Axisymmetric and Non-Axisymmetric Stretching of Sheet Metals by the Finite Element Method
Stretching process of sheet metals in both cases of axisymmetric and non-axisymmetric is analyzed. A rigid-plastic, normal anisotrop material is assumed and large strain formulation is applied. Triangular elements are used and stiffness equations of elements are obtained from virtual work principle. These nonlinear equations are linearized by Newton-Raphsons method and are solved by Gaussian el...

متن کاملStability Range for a Flat Graphene Sheet Subjected to In Plane Deformation
571 Graphene is a flat monatomic carbon layer where each atom has covalent bonds with its three neighbors (see Fig. 1a). Due to its unique mechanical, physical, and optical characteristics, graphene is promising for different technological applications. In recent years, the effects of significant elastic strains on the mechan ical and physical properties of graphene and other low dimensional ca...
متن کاملPrediction of Instability in Planar Anisotropic Sheet Metal Forming Processes
In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...
