This work aims to investigate the vibration behavior of porous three-directional functionally graded (3D-FG) microshells in thermal environments, where both mechanical and material properties vary along three spatial directions following a power-law distribution, based on modified couple stress theory (MCST). An isoparametric element is employed for uncoupled heat conduction analysis, followed by dynamic analysis using penalty solid with translation degrees freedom (DOFs) rotation DOFs per node. However, due strong nonlinearity temperature field 3D-FG microshells, obtaining exact values at integration points requires pretty dense mesh element. To overcome this issue, back propagation (BP) neural network utilized predict various gradient indexes, enhancing efficiency precision distribution calculation. Numerical results demonstrate effectiveness enhanced finite model. Furthermore, effects length scale parameter (MLSP), difference, indexes natural frequencies are investigated. It shown that higher structural stiffness weakens impact difference frequency.
