Description
Summary:The problem of uncertainty factor management in the description of mechanical stress nearby hatchways of multilateral form with rounded corners of fuzzy curvature in stretch thin plate is considered. Numerical and analytic methodology based on heuristical principle application of extension to transition to fuzzy set arguments in special analytical representations for estimated factors of stress concentration is proposed. Algorithm of fuzzy interval parameter spread of curve in corner points is described. Usage of proposed methodology in theoretical and applied researches on integrity problems of multiply connected thin-walled structure elements is characterized.
