| Summary: | Precision manufacturing demands control over interfacial bonding properties, which relies on understanding the structure–property relationships. The authors applied experimental–simulative approach to investigate these relationships, specifically: a. RVE models with incrementally increasing interlocking arrays were created to equate the increase in aluminum surface porosity and simulate shear loading, thereby validating the incremental quasistatic shear experimental results. b. Contact parameters were applied in RVE models to equate the nanostructures generated on the aluminum surface with meso/microstructures, verifying the superimposed contribution of nanoscale features on the bonding property. c. Interlock size and depth were adjusted within the same scale in RVE models, indicating that the interfacial bonding properties depend on the downsizing of interlocks, whereas the depth made few differences. d. By imposing multiple loading velocities on RVE models with increasing amounts of interlocks, the mechanical responses were amplified with the loading rate, and the obtained structure–property plot relationships were similar to those in quasistatic loading. Additionally, this work identified inherent linear relationship between shear strength and interface failure work from existing experimental and simulated results. In an experimental–simulative approach, this study systematically explores the aluminum/polymethyl methacrylate (Al/PMMA) interfacial mechanical response, offering insights into researching heterogeneous interfaces with interlocks. |
