NEAR TIP SINGULAR FIELDS FOR MODE I CRACK DYNAMICALLY PROPAGATING IN A POWER LAW COMPRESSIBLE MATERIAL

Near tip singular stress and strain fields of a mode I crack dynamically propagating in a power law compressible material under plane strains are considered. With J 2 flow theory and the rectangular components, this paper obtains the near tip asymptotic fields in which the singularities of stress and strain are different and the angular variations of field quantities are the same as those in elastic perfectly plastic materials.
