Studying thin plates with varying stiffness in a stretchy medium for improved electronics materials

What is it about?

This study explores how viscoelastic foundations affect wave dispersion in ceramic-metal functionally graded beams with microstructural defects. It uses a specialized theory for shear-deformable beams and examines the impact of viscosity damping on imperfect beams. Results highlight relationships between material properties like gradation, beam thickness, porosity, and foundation parameters, showing how these factors influence wave velocities, especially with low porosity.
