Static and dynamic analysis of hemispherical convex-concave composite plate (HCCP) using variational asymptotic equivalent model

• The VAM-based equivalent model of HCCP is established, and verified by comparing with 3D-FEM. • The static and dynamic behaviors of HCCP are systematically analyzed using 2D-EPM. • The effects of geometric and material parameters on buckling load and natural frequency are analyzed. • The details of local field distribution within unit cell of HCCP are well captured. • The DOFs of the 2D-EPM is greatly reduced, resulting in high calculation...
