Precast, prestressed concrete box girders are commonly used as superstructure components for short and medium span bridges. Their configuration and typical side-by-side placement make large portions of these elements inaccessible for visual inspectio

The aim of this work was to develop a method for optimizing both the design parameters and the mechanical properties of polymer-based nanocomposites using multi-objective optimization (MOO) methods. The objective was to maximize both the elastic modu

The effective application of vibration-based damage detection (VBDD) methods as a structural health monitoring approach depends largely on the accurate measurement of modal properties, particularly the mode shapes. However, the modal properties of br

The effects of different nano-structural phase shapes on the mechanical properties of a SiC/Cu interpenetrating phase composite (IPC) at the atomic scale are investigated by using molecular dynamics (MD) simulation. Two different geometrical models,

The effect of phase morphology on the elastic and plastic behaviour of interpenetrating phase composites (IPCs) was investigated using finite element (FE) modelling. Two different microstructural morphologies were modelled, one consisting of a three-

In vibration-based damage detection, changes to structural modal properties are tracked over time in order to infer the current state of damage or deterioration. As such, the ability to obtain reliable estimates of modal parameters, particularly natu
