In this paper, probabilistic models for structural analysis are put forward, with particular emphasis on model uncertainty. Context is provided by the finite-element method and the need for probabilistic prediction of structural performance in c[...]

This paper presents a hybrid analytical–computational mechanics formulation for an arbitrarily curved Timoshenko beam undergoing planar finite deformation and subjected to kinematic constraints in the form of fixed displacement and cross-linking[...]

This paper proposes a derivative-free two-stage extended Kalman filter (2-EKF) especially suited for state and parameter identification of mechanical oscillators under Gaussian white noise. Two sources of modeling uncertainties are considered: ([...]

In this paper, a damage assessment method for remotely inspecting the near-surface condition of multilayer composite systems is proposed. The method utilizes far-field steady-state electromagnetic waves reflected from the surface of multilayer c[...]

Design of infrastructure materials with inherent material damping may help dissipate energy during dynamic loading events such as earthquakes, thereby reducing structural damage and risk of collapse. One possible method to enhance damping of cem[...]

Early time transient waves multireflected in a finite pile, governed by a damped wave equation, are analyzed by a reverberation-ray matrix. The pile is surrounded by compacted soil, and the composite is modeled by elastic springs and viscous dam[...]

The cohesive crack model has been widely accepted as the best compromise for the analysis of fracture of concrete and other quasibrittle materials. The softening stress-separation law of this model is now believed to be best described as a bilin[...]
