5. Brief conclusions In the present study the stress tensor elements in the surroundings of crack and notch tips are effectively appraised via two approaches. The stress fields are estimated by continual and atomistic approaches. In the framework of the continuum mechanics approach it is connoted the usage of the classical theoretical solutions and finite element-based numerical solutions of continuum fracture mechanics whereas the atomistic approach is
