In this fast growing world, where technological advancements are influenced by more efficient and less expensive designs, there is a significant need of adopting methods and techniques that can support this thought process. To address this requirement, Finite Element (FE) modeling techniques were introduced as a viable solution. Specifically in case of mechanical structures, where prototype building and physical testing requires a lot of time and involves huge costs, developing an FE model that can predict its dynamic characteristics accurately is key to address the issue. However, with more reliance on FE models as a true representative of physical structures, there is a significant need to evaluate such models. This evaluation involves comparing the results obtained from simulating FE models with the results achieved from mathematical models and real world test data. In other words, such models need to undergo `verification’ and `validation’ before they can be used to predict reliable results for the future. In this research, a model verification, calibration, and validation case study is performed on a rectangular steel plate structure. The case study was based on a systematic approach that was used in an attempt to follow the Guidelines for Verification and Validation (V\&V) published recently by the American Society of Mechanical Engineers (ASME) and the American Institute of Aeronautics and Astronautics (AIAA). The accuracy of the model and the validation process was confirmed by modal correlation when the structure and the calibrated model were subjected to perturbed mass and constrained boundary conditions. The validation criteria were achieved using the calibrated model and the results obtained through validation criterion helped quantify the accuracy of the developed model under different boundary conditions.
