hi desertfox,
thanks for the help.
Is it possible that the prestressing occurs at a lenght smaller than the minimum working length always given that the stress is greater than the elastic limit of the material.
My question has to do with the prestressing of spring. A spring is prestressed to increase the working life of the spring by inducing wanted stresses within the material. This is done by setting plastically deforming the material when the spring is compressed for the first time due to the...
