Where the Lukzag modification introduces a shear correction factor $\kappa$ into the bending stiffness $D$:
$$ D \nabla^4 w - \rho h \frac\partial^2 w\partial t^2 = q(x, y) $$
Abstract This paper presents a comprehensive verification and validation study of the Lukzag theoretical model, utilized for the analysis of complex structural systems. While numerical methods such as the Finite Element Method (FEM) dominate current engineering practice, analytical models like the Lukzag approach offer computational efficiency and distinct insight into mechanical behavior. This study verifies the mathematical consistency of the Lukzag formulation and validates its predictive accuracy against experimental benchmark data and high-fidelity FEM simulations. Results demonstrate that the Lukzag model maintains a deviation of less than 5% from experimental results, confirming its viability as a reliable tool for preliminary design and theoretical analysis. 1. Introduction The development of simplified analytical models remains a critical aspect of structural engineering, offering rapid solutions where full numerical simulations are computationally expensive. The Lukzag model (potentially referring to advancements in folded plate theory or soil-structure interaction by researchers such as Gajewski et al.) proposes a semi-analytical approach to solving boundary value problems in elasticity.
The governing differential equation for the deflection $w$ is expressed as:
