• The S-D-S-ER model exhibited viscous behavior similar to composite materials, which contributed to its superior performance, while the D-S-ER model demonstrated more conventional mechanical behavior and a shorter lifespan. • The increased stiffness and fatigue resistance of the S-D-S-ER method, confirmed through quasi-static three point bending tests, highlight its potential to optimize structural designs. These findings emphasize the value of advanced numerical techniques, that is, the S-D-S-ER method, in enhancing the fatigue resistance and overall durability of structural components, paving the way for future innovations in material engineering and design optimization.
