This paper describes the use of a quadratic manifold for the model order reduction of structural dynamics problems featuring geometric nonlinearities. The manifold is tangent to a subspace spanned by the most relevant vibration modes, and its curvature is provided by modal derivatives obtained by sensitivity analysis of the eigenvalue problem, or its static approximation, along the vibration mo...

Electrodynamic shakers are utilized in many experimental modal tests and general structural dynamic testing. The physical aspects of shaker, stinger and transducer setup can result in anomalies that are often misunderstood. Many times measurement artifacts related to mounting and dynamic coupling between shaker, stinger and test object can appear, affecting test results. This paper overviews so...

Natural surfaces are often structured with nanometre-scale domains, yet a framework providing a quantitative understanding of how nanostructure affects interfacial energy, γSL, is lacking. Conventional continuum thermodynamics treats γSL solely as a function of average composition, ignoring structure. Here we show that, when a surface has domains commensurate in size with solvent molecules, γSL...

Purpose – Enterprise resource planning (ERP) systems enhance productivity and working quality by offering integration, standardization and simplification of multiple business transactions. The present study seeks to introduce a conceptual framework that investigates the way that human inputs (top management, users, external consultants) are linked to communication effectiveness, conflict resolu...

This session offers an open forum to discuss issues and directions of research in the areas of model updating, predictive quality of computer simulations, model validation and uncertainty quantification. Technical presentations review the state-of-the-art in nonlinear dynamics and model validation for structural dynamics. A panel discussion introduces the discussion on technology needs, future ...

With the progress in modeling dynamic systems new extensions in model coupling are needed. The models in classical engineering are described by differential equations. Depending on the general condition of the system the description of the model and thereby the state space is altered. This change of system behavior can be implemented in different ways. In this work we focus on three state-of-th...

Maintaining topic integrity in online discussions can be problematic for instructors. Understanding the underlying mechanisms of topic drift yields insight into how online classroom discussions can be effectively managed, enabling facilitators to assure conversational flow while limiting unproductive digressions. This paper presents an analysis of topic drift in asynchronous learning environmen...

Modeling of dynamic networks — networks that evolve over time — has manifold applications in many fields. In epidemiology in particular, there is a need for data-driven modeling of human sexual relationship networks for the purpose of modeling and simulation of the spread of sexually transmitted disease. Dynamic network data about such networks are extremely difficult to collect, however, and m...

In this paper we propose a new method for stable numerical integration of the dynamic Cosserat equations for rods, which constitute a mechanical framework for the physically based modeling of slender structures like DNA strands, drill strings, marine cables or human hair. Our integration method is well-established in the field of structural dynamics and has the major advantage of unconditional ...
