P., Registration Date 22-07-2005 Organization Karpenko Physico-Mechanical Institute of the National Academy of Sciences of Ukraine popup.description2 Using the method of singular integral equation, a general approach to solving the boundary value problems of elasticity theory for finite or infinite multiconnected domains with cracks and holes as well as with angular points at the boundary contours has been developed, the power singularities of stresses at those points being taken into account. The deformation fracture criterion for homogeneous bodies with the angular notches under plane strain condition has been constructed. It was proved experimentally on the beam specimens with an angular notch under thee-point bending. A new method for solving dynamic problems of fracture mechanics based on time-finite differences and singular integral equations on spatial variables has been developed. Two approaches to investigation of the elastic-plastic bodies with rounded notches, when the plastic zone envelopes the hole contour only partly, has been developed.
