    A general survey of the results of elastic stress analyses of cracked bodie is the basic objective of this work. The stress-intensity-factor method ofs representing results is stressed and compared with other similar methods. All three modes of crack-surface displacements are considered, as well as specialized results applicable to plate and shell bending. Results for various media (for example, anisotropic, viscoelastic, or nonhomogeneous) are contrasted with the analysis of homogeneous isotropic media. The accuracy of the representation of the crack-tip stress fields by stress-intensity factor methods is discussed, pointing out some limitations of applicability. Methods of estimating and approximate analysis for stress-intensity factors in complicated practical circumstances are also discussed.
