Coeficientul de intensitate al tensiunilor pentru fisura plană în formă de paralelogram

Abstract

The description of stress increase applied at the top of the crack with the known shape and dimensions is attributed to the stress intensity coefficient, used in the rupture mechanics. Upon reaching the critical value of the coefficient, rapid crack growth occurs in any structure that contains it. When assessing the strength of the material, it is necessary to take into account the tension intensity coefficient.
