Wire spacing in both directions influenced mechanical performance. In the direction of strain (length-wise), increased spacing proved beneficial, with more widely separated microwires exhibiting both fewer cracks and delayed crack initiation (Fig. , Fig. and Fig. ). Perpendicular to the direction of strain (width-wise), the opposite trend emerged: decreased spacing enhanced performance, with more closely packed microwires demonstrating reduced and delayed cracking (Fig. , Fig. and Fig. ). FEA simulations for length-wise spacing aligned well with experimental results (Fig. ), yielding ultimate tensile stress values between 300-460 MPa. However, the widthwise spacing simulations revealed more complex behavior. While the maximum stress analysis suggested better performance with wider spacing (Fig. ), a comprehensive examination of all microwires in each group (Fig. ) revealed a nuanced pattern: samples with smaller spacing began failing earlier, but those with larger spacing showed a more rapid transition from fully intact to fully broken states. This apparent discrepancy between maximum stress predictions and experimental observations suggests that the current model may require refinement to fully capture the complex mechanical interactions in closely packed microwire arrays.
