However, for various reasons, the concept of a generalized plane stress state has been widely accepted in analytical mechanics and was adapted in general engineering design and testing, including various procedures of experimental stress analysis, mainly photoelasticity. As a result, various technically important concepts, such as geometric stress concentration factors for notches in plates, or stress intensity factors in-plane fracture mechanics, have been developed on the basis of the concept of average stresses. The empirical evidence presented in this paper shows that in regions of notches and cracks in plates all components of a three-dimensional stress state exist and depend also on the thickness coordinate. This evidence has been produced using the resistance strain gages and isodyne techniques. The actual stresses and their major functions, such as the equivalent stresses, are 20-3012aPindera, J.T.12aLiu, X.40uhttps://drive.google.com/file/d/1gTiEfdaUd9qgCt4rku1HpY5jY8rlP_HH/view?usp=drivesdkzPara ver el documento ingresa a Google con tu cuenta: @cicy.edu.mx  2LoccREF1250602s9999    xx |||||s2   |||| ||und|d  c22719d22719  00102Loc40708F1aCICYbCICYcREd2025-06-25l0oB-12573r2025-06-25 15:38:59w2025-06-25yREF1
