Flow StressStrain RateEffect of Temperature in Metal FormingFriction and Lubrication in Metal FormingDifferent Types of Metal Forming ProcessesDuring a metal forming operation, it is important to know the force and power that will be needed to accomplish the necessary deformation. The stress-strain graph shows us that the more a work piece is deformed plastically, the more stress is needed. The flow stress is the instantaneous value of the force necessary to continue the yielding and flow of the work material at any point during the process. Flow stress can be considered as a function of strain. The flow stress value can be used to analyze what is gSee more on thelibraryofmanufacturingThe Handle Wonder Cover for Hot Door Handles - - The Neoprene material is the same material used for can and bottle coolers and also wet suits.
