Reduction of stress intensity factor in a uniaxlally loaded cracked plate

Abstract EN

This paper presents work in progress, concerning the reducing of stress intensity factor values for finite width plates by using auxiliary circular holes, the analysis is done by using the finite element method.

To find the stress intensity factor “ SIF ”, the ANSYS packages was implemented to evaluate the SIF by using th Finite Element of Fracture Mechanic.

It had found out that the SIF is reduced to 56 % by using the auxiliary hole in the plate, the dynamic load of unit step input had been test to show the validity of this method, which is better to prevent crack from propagation.
