effectiveness of composite patch repairs, especially when considering factors such as moisture ingress and temperature variations that can exacerbate these defects.

Figure 1: (a) A center cracked plate repaired by composite patch bonded using adhesive (b) Direction of fiber orientation of composite patch. As shown in Fig. 2 (b) a square void measuring 2 mm × 2 mm has been modeled for every crack length in the adhesive layer at six distinct places. Fig. 2(a) depicts the quarter part of the defect-free adhesive area.
