This study demonstrates static bending behavior in functionally graded sandwich spherical shells, pointing to enhanced accuracy through smoothed finite element methods.
Key Points
The ES-MITC3i approach effectively improves accuracy and convergence rate in bending analysis.
Numerical simulations indicate significant improvements in results compared to conventional methods.
The approach utilizes a strain smoothing technique to avoid shear locking in the bending analysis.
The material properties are based on a power-law distribution through the shell thickness.
