The Pseudocaustics for the Evaluation of the Order of Singularity in Stress Fields

Conference paper


The only analytic techniques which have been used up-to-now for the evaluation of stress singularities are the eigenfunction-expansion theory and the application of Mellin transform. The first attempt to study stress singularities was made by Williams (1952), who derived the characteristic equations for wedges, by making the assumption that the order of singularity is a real number. The same assumption has been accepted by Kalandiia (1969), for evaluating the orders of singularities at corners. Bogy (1968) and Dundurs (1969) have derived solutions for stress singularities in wedges, by using a straightforward application of the Mellin transform.
