The problem of the contact between a broken stringer and an elastic infinite strip containing a vertical edge crack. (English. Russian original) Zbl 1331.74123
Int. Appl. Mech. 51, No. 2, 176-186 (2015); translation from Prikl. Mekh., Kiev 51, No. 2, 66-77 (2015).
Summary: The method of singular integral equations and the combined numerical/analytical method of mechanical quadratures are used to effectively determine the stress-strain state of an infinite elastic strip with an edge crack reinforced with a broken stringer. It is shown that if the length of the crack and the width of the strip are constant, an increase in the stiffness of the stringers leads to an increase in the stress-intensity factor K I and the maximum crack opening displacement, which, in turn, increases the probability that the crack will start growing.
