STRESS SINGULARITIES AT THE APEX OF A DISSIMILAR ANISOTROPIC WEDGE

The complex form of the characteristic equation for the stress singula rities of the order r(lambda-1) (0 < Re [lambda] < 1) for the dissimil ar anisotropic wedges is derived Special attention is then focused on the problems that are composed by two orthotropic materials. For such problems the characteristic equation is expressed in real forms from w hich the dependence of the singularities on the material parameters an d wedge angles is investigated. The case of a single free-fixed wedge problem is particularly studied in derail. Numerical results for sever al special wedge geometries are also presented.
