Damage Rate Laws and Failure Statistics for Lumped Coupled-Field Systems via Averaging
Arjun Roy, Joseph P. Cusumano
We study the non-linear dynamics and failure statistics of a coupled-field fatigue damage evolution model. We develop a methodology to derive averaged damage evolution rate laws fr…

Model Reduction of a Flexible Nonsmooth Oscillator Recovers its Entire Bifurcation Structure
Suparno Bhattacharyya, Joseph. P. Cusumano
We study the reduced order modeling of a piecewise-linear, globally nonlinear flexible oscillator in which a Bernoulli-Euler beam is subjected to a position-triggered kick force an…

Damage nucleation phenomena: Statistics of times to failure
S. G. Abaimov, A. Roy, J. P. Cusumano
In this paper we investigate the statistical behavior of an annealed continuous damage model. For different model variations we study distributions of times to failure and compare…
