A unified viscoelastic-viscoplastic constitutive framework for optically clear adhesives: Experiments, modeling, and FE validation (opens in new tab)

Optically clear adhesives (OCAs) are extensively employed as bonding layers in display manufacturing. As compliant interlayers in foldable display stacks, they undergo pronounced time and temperature -dependent deformation during repeated bending, which makes reliable constitutive characterization essential for accurate stress prediction and design optimization. Therefore, accurately characterizing their mechanical behavior is fundamental to bending-stress analysis and design optimization of ...
