In the present work, a specific three-point bending test is applied to evaluate how roughness can impact bond strength (adherence) and mechanism of interfacial failure initiation. The study conducted using an aluminum alloy 2024-T3 as substrate DGEBA (polyepoxide bisphenol A diglycidyl ether) /DETA (diethylenetriamine) adhesive, considering different abrasive surface treatments. An optimal reac...

The combined finite–discrete element method (FDEM) based on the cohesive zone model (the CZM) achieves cracking simulation by inserting elements between solid elements. In this study, three-point bending fracture tests of frozen soil were simulated using FDEM CZM. Firstly, sensitivity parameters was analyzed. Secondly, through a series simulations test soil, it found that with reasonable values...
