Nonlinear bending of elastoplastic functionally graded ceramic-metal beams subjected to nonuniform distributed loads

作者:

Highlights:

• Nonlinear bending of FG ceramic-metal beams subjected to nonuniform distributed loads is studied.

• TTO model is employed to evaluate elastoplastic properties of the FG beams.

• Nonlinear finite element formulation is formulated and used in the study.

• Effect of material inhomogeneity, plastic deformation, loading type on nonlinear response is studied in detail.

• Formation and propagation of plastic zone during loading process are examined and discussed.
