14、93-EB/JUI.1988 Introduction The International Symposium on Mechanical Relaxation of Residual Stresses was con-vened on April 30,1987,in Cincinnati,Ohio,with speakers from five countries participating.The objective was to obtain a better understanding of the processes by which residual stresses are r
15、elaxed by certain mechanical treatments.This volume presents the peer reviewed and edited proceedings of that specialists symposium.One of the interesting adjectives that is often used to describe residual stresses is in-sidious.This is because residual stresses are present in virtually every solid
16、material or component but,because we cant see them and because without some careful and complex measurements we dont know how severe they might be,we sometimes tend to forget that they are there.Yet,their effects can be significant,even catastrophic.In spite of their insidious nature,we do know some basic and important things about residual stresses.We know,for example,that residual stresses and applied stresses are algebraically additive within the elastic range and,thus,residual stresses can b
