The determination of response statistics of multi-degree-of-freedom nonlinear systems with singular matrices subject to combined deterministic and stochastic excitations. The application of the proposed method in piezoelectric vibration energy harvesting devices. Code-compliant stochastic dynamic analysis of nonlinear structural systems with fractional derivative elements. Stochastic incremental dynamical analysis for nonlinear structural systems with fractional derivative elements exposed to stochastic excitations aligned with contemporary aseismic codes. First excursion probability of nonlinear dynamic systems subject to imprecisely defined stochastic Gaussian loads.
