Presented paper deals with suggestion of stability criterion of V-notched solids under simple loading mode I or II or under combined loading mode I+ II xhe methods used to propose the stability criterion are based on an analogy of behaviour of cracked and notched bodies. The paper presents an approach of criterion suggestion and a computational method for deterrruning the values ofthe controlling physical quantities. Corresponding calculations are performed using the finite element method (ANSYS).
