Uniform SnO2 fibers were prepared from the electrospinning method in this paper. The mechanical properties of a single SnO2 fiber were characterized by three-point bending experiments with atomic force microscopy. Finite element method was employed to simulate the shape of the SnO2 fiber during the bending process. The elastic modulus of SnO2 fibers increased with the calcined temperature. A high elastic modulus of 72.59 GPa was obtained with a diameter of 160 nm. The results indicate that atomic force microscopy tips penetrated the surfaces under maximum loading. The force-displacement curve from simulation is in accordance with the results from experiments by using AFM and theoretical calculation. The equivalent strain nephogram indicates that the maximal strain is about 0.0143 at the midpoint of the fiber.
