Abstract

Newly developed explicit, unconditionally stable approaches for the analysis of the dynamics of linear/nonlinear shell structures are proposed, and the application of these approaches to CRAY computing environment is demonstrated. The computational and implementation aspects including the numerical evaluation of Virtual-Pulse (VIP) is discussed. The VIP methodology and the Newark family of methods are compared in terms of accuracy and computing time. Numerical results indicate that VIP has significantly reduced computing time compared with Newark family of methods which are commonly used.
