Webb7 okt. 2015 · This book is about Strength of Materials. It is not a handbook rather intended as a textbook for the present and hopefully future generations of Strength of Materials. … WebbThe yield strength is often used to determine the maximum allowable loadin a mechanical component, since it represents the upper limit to forces that can be applied without producing permanent deformation. In some materials, such as aluminium, there is a gradual onset of non-linear behavior, making the precise yield point difficult to determine.
