Abstract:

In this study, the inclusion into a circular holed, infinite plate is studied for different conditions. A cylinder with a radius of d is inserted into the circular hole with a radius of r, on an infinite plate. In the first part of the study, the inclusion of the specified cylinder with a torsion M0 on it, to the circular hole of an infinite plate without axial loading is studied. The same problem is studied; in case, the plate had been both one and two axially loaded. Since the problem has linear solutions; via superposition technique, solutions for different loading conditions are obtained. In this part, two different methods to find the pressure between the included cylinder and the plate, are performed. In the first method; it is assumed 1hat the pressure is not dependent on 9 ; but, on the second method; it is assumed that pressure is dependent on 0. The results show that the stresses change abruptly whether there is pressure in between the plate and the inclusion. In the second part of die study, die results found in the first part are used. The effects on the stresses by using plate and inclusions made of different materials is investigated. As a result; it is seen that the usage of different materials is not a major effect on the magnitude of the pressure in between the plate and the inclusion. All along the study, the investigations are all performed according to the value of the interface. As a result; it is seen that the stresses are directly dependent with the the value of the interface.
