Abstract
Numerical procedures for analyzing transient responses of composite structures with time and temperature dependent linear viscoelastic damping have been developed in the time domain using variational principles and the Newmark average acceleration method. Recursion formulas also have been obtained in order to reduce computer storage and only the previous time solution is required to compute the next time solution. Verification studies were conducted to evaluate the accuracy and convergence of the present numerical algorithm and they show that the numerical solutions agree well with the analytical ones. As examples, the dynamic transient responses of long cantileveredT300/934 composite Euler beams subjected to unit step and impulse loads were calculated using the presently developed procedure.
