EFFECT OF PIEZOELECTRIC AND STIFFENER ON DISPLACEMENT OF THE SHALLOW CYLINDRICAL COMPOSITE SHELL SUBJECTED TO SHOCK WAVE
Keywords:Composite shell, stiffener, piezoelectric
The vibration of the composite stiffened cylindrical shell with piezoelectric layers subjected to shock wave is presented in this paper. The differential equations which describe the nonlinear oscillation dynamic of the shell are solved by the Newton-Raphson iterative method in combination with the Newmark direct integration method. Numerical results are solved for the structures subjected to the effect of shock wave in MATLAB software. On the basis of the program, the effect of piezoelectric and stiffener on the nonlinear oscillation of the cylindrical composite shell are considered.
