WebJan 21, 2024 · The Goodman theory states that for all the in-between cases you draw lines from A to B and from A to B' to define the endurance limits in the presence of non-zero average stress (midrange stress). This hypothesis is supported from testing (in some other page in Shigley book) and from the elastic theory of solids. WebGoodman The Goodman criterion is very inaccurate for the purpose of estimating an equivalent completely reversed stress. Its inaccuracy is almost always in the very conservative sense, in that it predicts a higher equivalent completely reversed stress than is validated by experiment. bread and chocolate cayman islands
