Common Question from students--- Where does metal get its strength? I know that edges increase strength, and angles/folds help as well, but in terms of overall tensile strength versus thickness or number of angles/bends. ----------------- I am not sure I am following your question, but I'll try to elaborate on metal strength. Metals get their strength from their material make up (i.e. their atomic makeup) and microstructure characteristics. Different metals have different bits of material in them that bring out a certain microstructure. The metal can also be manufactured a certain way to make its microstructure different as well. These two things really define how much stress a

Unformatted text preview: metal can withstand before it yields. This measurement of stress (or strength of the metal) is in units of force per area, which in English units is lbs/in^2. Metal handbooks will give you values of yield strength and ultimate tensile strength for various metals. Now if you know the force that will be placed on a metal, you can determine the area over which you can disperse this load in order to never reach the yield point of the metal. This is what I believe is your question in regards to folds, angles or thickness. Different metal shapes have different cross sectional areas that are the in^2 part of the equation....
