Paragraph starter

Finite Element Analysis (FEA) provides a powerful method for predicting the mechanical behaviour of complex structures. Research by Chen et al. (2020) demonstrated that FEA models could accurately simulate the stresses experienced by flexible display modules under various conditions, such as folding and impact, with simulation results closely aligning with experimental data. This highlights the utility of FEA in guiding the structural design and material selection for products incorporating flexible technologies, enabling designers to identify potential failure points and optimize durability early in the design process.
