Abstract: Starting with the analysis of the force and deformation of an infinitesimal mass and based on the fundamental theories of elastic mechanics such as the Newton law,continuous hypothesis and extensive Hooke law,we study the problem of energy transfer of transverse wave in a continuous media. Under the conditions of the minute reform hypothesis,no initial stress hypothesis, uniform and isotropic medium hypothesis, we analyze the prompting factor and dynamical image and show the essential character and elementary law of energy transfer of transverse wave.
