Paragraph starter
Finite element modeling, as demonstrated by Charuk et al. (2024), offers a powerful approach to predicting the dynamic response of plywood. By incorporating orthotropic material models and updating the simulation with experimental frequency response functions, high accuracy (average relative errors below 2% for panels) can be achieved, enabling more reliable design decisions for structures subjected to dynamic loads.
