Abstract This work intends to present a novel numerical approach for studying the vibration behaviours of variable angle tow (VAT) composite structures in their quasi-static nonlinear equilibrium states. methodology is able predict buckling load, investigate natural frequencies variation progressively higher loads, and provide means verifying experimental Vibration Correlation Technique results...

This paper presents the nonlinear dynamical post-buckling analysis of an uncertain cylindrical shell. The proposed approach is adapted to the dynamical analysis of geometrically nonlinear structures subjected to a stochastic ground-based motion in the presence of both system parameter uncertainties and model uncertainties. The structure is modeled by a large finite element model using 3D elasti...

The article is focused on a two-dimensional geometrically nonlinear formulation of Bernoulli beam element that can accommodate arbitrarily large rotations cross sections. based the integrated form equilibrium equations, which are combined with kinematic equations and generalized material leading to set three first-order differential equations. These then discretized by finite differences bounda...
