Clastics wave Summarize When elastic object bears loads in static force equilibrium conditions, not all the parts of object has displacement, distortion and streSs At the beginning of the loads, the parts which are more far from the loads have no impacts. After then, the displacement, distortion and stress caused by loads transmit to other places in a finite speed of wave This wave is called elastic wave his chapter will first give movement differential equations of elastic objects, then introduce some conceptions of elastic wave and simplify the equations according to different elastic waves, at last give the speed transmitting formulas of wave in infinite elastic objects
5 Summarize: When elastic object bears loads in static force equilibrium conditions, not all the parts of object has displacement, distortion and stress. At the beginning of the loads, the parts which are more far from the loads have no impacts . After then ,the displacement , distortion and stress caused by loads transmit to other places in a finite speed of wave. This wave is called elastic wave. This chapter will first give movement differential equations of elastic objects, then introduce some conceptions of elastic wave and simplify the equations according to different elastic waves, at last give the speed transmitting formulas of wave in infinite elastic objects
