Engineering Reports, Volume 8, Issue 2, February 2026.Adhesively bonded steel‐to‐hybrid sisal–glass/HDPE joints were experimentally and numerically assessed using a variational method and CZM‐based FEM. Optimal overlap (10 mm) and adhesive thickness (0.5 mm) achieved peak shear stress of 32 MPa, confirming lightweight, sustainable automotive panel potential. ABSTRACT This study investigates the mechanical
