title = "Uncertainty quantification in analytical and finite element beam models using experimental data",
abstract = "This study describes the quality of model formation for free vibration of beam structures under uncertainty. The key issues are that all analytical and numerical finite element (FE) models contain uncertainties due to the tolerances in topological parameters, assumptions made, material parameters, boundary conditions. Two well-known Euler-Bernoulli and Timoshenko beam theories have been compared. At FE level, various elements available for modeling of beam structures in ABAQUS are compared and evaluated. Experimental modal analysis have been performed on beam specimens to validate the results from analytical and FE models due to parameter uncertainties. It is shown which element types are required to allow minimal deviation from the experimental results considering uncertainties.",
