Assessment of climate induced damage in decorated oak wooden panels

Climate induced damage in decorated oak wooden panels is considered to be a high risk for the preeminent museum collections. To advise museums on the development of future sustainable preservation strategies and to define rational guidelines for indoor climate specifications, climate induced physical and mechanical damage has been analysed in a...

Generalized grain cluster method for multiscale response of multiphase materials

A multiscale approach termed the generalized grain cluster method (GGCM) is presented, which can be applied for the prediction of the macroscopic behavior of an aggregate of single crystal grains composing a multiphase material. The GGCM is based on the minimization of a functional that depends on the microscopic deformation gradients in the...

Crystallographically based model for transformation-induced plasticity in multiphase carbon steels

The microstructure of multiphase steels assisted by transformation-induced plasticity consists of grains of retained austenite embedded in a ferrite-based matrix. Upon mechanical loading, retained austenite may transform into martensite, as a result of which plastic deformations are induced in the surrounding phases, i.e., the ferrite-based...

Numerical modelling of transformation-induced damage and plasticity in metals

Crystalline damage development during martensitic transformations

A recently developed thermo-mechanical model [1] is presented that can be used to simulate the interactions between martensitic phase transformations and crystalline damage growth at the austenitic grain level. Subgrain information is included in the model via the crystallographic theory of martensitic transformations, see also [2,3]. The state...

The Mechanical Behaviour of Ballasted Railroad Tracks

Steady state response of a granular layer to a moving load - A discrete model

This paper discusses the steady state response of a rigidly supported, granular layer to a moving load. Accordingly, the dynamic behaviour of a ballast layer under an instantaneous train axle passage is simulated, where the rigid support reflects a substratum that is much stiffer than the ballast layer, e.g. ballast in a concrete railway tunnel...

Inklemeffecten bij steenzettingen op dijken: Eindige-elementenstudie naar geometrisch- en fysisch niet-lineair gedrag van blokkenmodellen

In dit rapport is via numerieke technieken die deels zijn geverifieerd aan experimentele resultaten van een houten blokkenmodel, een fundament gelegd waarop het fenomeen inklemming bij steenzettingen bestaande uit losse elementen, wordt ontleed. Een belangrijke conclusie uit dit rapport is dat inklemming bij toplagen op dijken afhankelijk kan...
