Abstract:

Based on the general theory of shell surface,the geometry equations and balance equations of arbitrary shape functionally graded material shells are established in this paper.Also,material character graded distribution along the shell thickness is imported in the physics equations,the general fundamental equations,boundary conditions and initial conditions with membrane-bending coupling of functionally graded material shells are established,which can be applied to analyze various functionally graded shells as a theoretical foundation.
