This thesis investigates the influence of finite specimen dimensions on residual stress evaluation using the hole-drilling method with digital image correlation (DIC). Standard evaluation procedures assume an infinite body, which neglects boundary effects that become significant in small components.
Finite element simulations of the hole‑drilling process were performed in ANSYS for various near‑edge configurations. Calibration coefficients for the infinite‑body case were determined and used in a MATLAB algorithm for residual stress evaluation. The influence of free edges was quantified by analysing relative errors in the calculated stresses for various stress states and geometries.
To reduce the influence of boundary effects, an iterative correction approach was proposed, in which the measured displacement field is modified using correction functions updated through a fixed-point scheme. The method is applicable under a set of assumptions discussed in the thesis, including uniform residual stresses.
The proposed approach was validated and demonstrated accurate stress reconstruction across different geometries, stress states, edge distances, and hole geometries. The results confirm that the method effectively compensates for free-edge effects and extends the applicability of the hole-drilling method with DIC to  specimens with finite dimensions.
