The fundamental equations of nonlinear flexural vibration for a rectangular elastic plate are solved approximately by employing a method of successive approximation, and the influences of temperature changes and large amplitudes on the period of free vibrations are established. Some numerical examples are given for a plate with hinged and immovable edges, and it is shown that the above effects are considerably large and cannot be neglected even when the temperature changes are small.
