The Neuber-Novozhilov approach is proposed for description of the stress distribution and crack opening in the prefracture zone in the vicinity of rupture cracks when solutions of the classical elasticity theory has a singular component. The stress distribution in the classical Leonov-Panasyuk-Dugdale model is chosen for a null approximation. Modification… CONTINUE READING
