The elastoplastic analysis of functionally graded materials using a meshfree RRKPM
作者：
Highlights：
• The RRKPM for elastoplastic problem of FGMs is proposed.
• Combining with the Galerkin weak form, the corresponding formulae are derived.
• The different functional gradient indexes are analyzed.
• The scaling factor, the loading steps and the node distributions are discussed.
• The RRKPM has excellent accuracy and convergence.
