A physically motivated reduced-order modal energy technique for ARMA spectrum estimation
A reduced-order modal energy (ROME) technique for spectrum estimation is introduced. In this technique the transfer function of a higher-order autoregressive (AR) model of a power spectrum is decomposed into partial ...
A residual flexibility approach for decoupled analysis of nonlinear, nonclassically damped systems of combined components
A residual flexibility approach for the analysis of systems comprised of multiple components subjected to dynamic loading is presented. In it, the reactive forces at the junctions of the components are computed directly ...
Application of Markov chains to the critical element model for determining the fatigue life of composites
A stochastic model for predicting the lifetime of composite laminates subjected to multiaxial fatigue loading is proposed. The model is based on the application of Markov chains to the well known "critical element" model ...
Plasticity, localization, and friction in porous materials
Original variations of two-invariant rate-independent plasticity models capture many features of the homogeneous behavior of porous materials. All of the variations proposed are based on a simple 7 parameter critical state ...
