Every acceleration or deceleration causes inertia forces and as a consequence elastic waves. Of course, such dynamic loading situations often occur in structural applications of materials. The consequences of such dynamic loading on designing with ceramics are considered on the example of a new dynamic tension test. First, the test device is described, and the resulting loading situation is car...

Structural health monitoring is an important aspect of maintenance for bridge columns in areas of high seismic activity. In this project, recently developed piezoceramic-based transducers, known as smart aggregates (SA), were utilized to perform structural health monitoring of a reinforced concrete (RC) bridge column subjected to pseudo-dynamic loading. The SA-based approach has been previously...

Response of soil depends on both the mechanical properties of soil itself and the nature of loading. Many geotechnical engineering problems are associated with dynamic and cyclic loadings, such as ocean wave or ice loading applied on foundations of offshore structures or bridges, dynamic loading applied on foundations of offshore wind power structures, ocean wave loading on harbor structures, s...

A large percentage of the railway bridges in the UK rail network and around Europe are of riveted construction exceeding in many cases 100 years of age. The remaining fatigue life of these bridges is difficult to estimate due to the uncertainties regarding the fatigue behaviour of wrought-iron and older steel material, which was used for their construction, as well as the actual loading and the...

During ascent of a space vehicle system from its launching pad, the noise generated by its propulsion system creates considerable vibratory motion in the vehicle structure. Consequently, any component and/or payload attached to the structure will experience a dynamic loading condition. Predicting these acoustically induced "random" loads is difficult because of the complexity of the acoustic en...

In this study, material flow from decentralized supermarkets to stations in mixed model assembly lines using tow (tugger) trains is investigated. Train routing, scheduling, and loading problems are investigated in parallel to minimize the number of trains, variability in loading and in routes lengths, and line-side inventory holding costs. The general framework for solving these problems in par...

In recent years, thin-walled accordion tubes under axial cyclic loading due to their appropriate energy absorption mechanism and behavioral characteristics were suggested as hysteretic metallic dampers. The effectiveness of accordion metallic damper (AMD) to protect and mitigate the response of structures under seismic loading is well established both experimentally and analytically. In this pa...

We present a T E X macro package for generating the arabic writing from a standardized ASCII input notation. It can handle partial or full vocalization, and generates automatically most of the common ligatures. There is limited support for Farsi, Urdu, and Pashto. ArabT E X is compatible with Plain T E X and also most L a T E X environments; arabic and other material can be mixed freely. For sp...

Offshore anchor piles are seafloor moorings that keep the position of floating structures during a harsh environment. These piles are usually subjected to a wide range of monotonic and cyclic lateral-to-oblique pullout forces. Centrifuge tests were carried out to study the behavior of offshore anchor piles under mooring forces in saturated dense sand. The tests were carried out at different loa...
