Nonlinear torsional waves propagating along an infinite isotropic cylinder are considered. The hyperelasticity of the cylinder
is described by the Murnaghan potential. An approximate analytical solution of the problem is obtained. The evolution of the
initial waveprofile in cylinders made of composite materials reinforced with microscale particles is simulated numerically.
It is shown that the approximation used to describe the variation in the amplitude inward the cylinder is quite accurate.
Three-dimensional plots of evolution are presented

The nonlinear wave equation is solved analytically in cylindrical coordinates using the third-order approximation of the Hankel
function. The second-order and third-order solutions are compared. The evolution of the initial wave profile is simulated
numerically for different initial frequencies

Summary A numerical technique is proposed to obtain the solution for the transient torsional wave propagation in a transversely isotropic cylinder when a torque is suddenly applied to its end surface. The dynamic behavior in the vicinity of the impact end of the transversely isotropic cylinder is studied. The stability and convergence of the present numerical technique and the validity of the numerical solution are examined. 相似文献
