I have a question, is it feasible that a flat plate spring

Customer Question

Hello
JA: Hello. What is your issue regarding?
Customer: I have a question, is it feasible that a flat plate spring steel could be formed into 145 degree bend and have the range of motion out to 0 degrees without reaching the yield point or deforming?
JA: OK. Is there anything else important you think the Structural Engineer should know?
Customer: Not at this point

Hello

to have a spring steel strip with an arc of movement of 35 degrees sounds quite reasonable to me

as with any material steel will bend and recover providing its not taken past its elastic limit and spring steel's elastic limit is very close to its point of UTS ( ultimate tensile stress)

the trick to giving this sort of spring a long life is the aspect ratio of the strip so the thickness of the material should be as thin as possible for the amount of force required as the thicker the material will need a longer strip to keep the strain to acceptable levels

so it will depend of how much force you need the spring to make and how much space you have to package it
