DRAWING AND ITS PROCESSES Drawing is a metalworking process which uses tensile forces to stretch metal. It is broken up into two types: sheet metal drawing and wire‚ bar‚ and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis. For wire‚ bar‚ and tube drawing the starting stock is drawn through a die to reduce its diameter and increase its length. Drawing is usually done at room temperature‚ thus classified a cold working process

perpendicular to this direction define principal directions‚ and the principal stresses do not vary on these planes. 2. Although effects of surface friction are included in the force balance‚ these do not influence the internal distortion of the metal or the orientation of principal directions. 3. Plane sections remain plane; thus the deformation is homogeneous in regard to the determination of induced strain. Plane Strain Compression of a Block

WHAT IS METAL? A metal is a chemical element that is a good conductor of both electricity and heat. Metals are malleable and ductile and have lustrous appearance. They have moderate to high physical constants and high tensile strength. Metals are further divided into two main groups - ferrous and non ferrous metals. TYPES OF METAL • FERROUS METAL These are metals which contain iron. They may have small amounts of other metals or other elements added‚ to give the required properties

Stretch forming is performed on a stretch press‚ in which a piece of sheet metal is securely gripped along its edges by gripping jaws. The gripping jaws are each attached to a carriage that is pulled by pneumatic or hydraulic force to stretch the sheet. The tooling used in this process is a stretch form block‚ called a form die‚ which is a solid contoured piece against which the sheet metal will be pressed. The most common stretch presses are oriented vertically‚ in which the form die rests on a

The five main categories of theories are Neuroscience‚ Psychodynamic‚ Behavioral‚ Cognitive‚ and Humanistic. Each category contains a very large history scaling all the way back to when Hippocrates or Aristotle roamed the earth. Once the category has

Metals and Non-metals Elements are divided mainly into two groups on the basis of physical and chemical properties – Metal and Non-metal. Metals: Part - I Physical Properties of Metals:- Hardness:- Most of the metals are hard‚ except alkali metals‚ such as sodium‚ potassium‚ lithium‚ etc. Sodium‚ potassium‚ lithium etc. are very soft metals‚ these can be cut using knife. Strength:- Most of the metals are strong and have high tensile strength. Because of this big structures are made using metals
