A Hermite interpolation element-free Galerkin method for functionally graded structures

作者：

Highlights：

• A HIEFGM for functionally graded structures is proposed.

• Hermite interpolation is used for approximation to improve the accuracy.

• Some important parameters on the performance of the HIEFGM are analyzed.

• HIEFGM is better than the conventional IEFGM in accuracy and convergence.
