Short summary
In summary, this study develops and validates an advanced beam element formulation that successfully addresses two critical challenges in structural analysis: accurate modeling of variable cross-sections and robust simulation of geometric nonlinearity. The comprehensive validation framework demonstrates the method's reliability across multiple benchmark cases, establishing its potential for engineering applications requiring precise analysis of tapered beam structures under large deformations.
