AStress concentrations occur when there are irregularities in the geometry or material of a structural component that cause an interruption to the flow of stress. This arises from such details as holes, grooves, notches and fillets.
material and geometry of the part
i think value of stress concentration factor depends upon geametry of the part , because stress concentration comes into picture due to abdrupt change in the geometry of the section .
