A numerical model for corrosion pit propagation under mechanical loading is presented. The level set method is used for corrosion front tracking and also enables the domain to be split into a solid and a pit domain. In the pit the diffusion of atoms originating from the dissolution process occurring at the pit front is simulated. The model is...

De huidige arbeidsmarkt is onvoldoende toegerust op de uitdagingen van deze tijd, of dat nu de klimaat- of energietransities zijn, de technologische ontwikkelingen (digitalisering, AI) of grote ‘externe’ schokken zoals economische crises en de huidige covid-19-pandemie. Bovendien stagneert in Nederland al decennia de productiviteitsgroei. Een...

Nee, dit is geen jammerklacht over een arbeidsmarkt die op slot zit door slecht beleid, destructieve bonden of inhalige werkgevers. Dit gaat over de theorie van de arbeidsmarkt die te vinden is in de inleidende hoofdstukken van economische leerboeken. Die werkt niet.

This study presents calibration and validation of a cohesive extended finite element model for fatigue crack propagation in ductile materials. The approach relies on a separation between plasticity around the crack tip and fatigue crack growth at the crack tip such that the influence of plasticity on fatigue driving forces is predicted. This...

De coronapandemie heeft ingrijpende gevolgen voor de Nederlandse economie en de arbeidsmarkt, nu en in de nabije toekomst. Om te voorkomen dat de werkgelegenheid te veel daalt en de werkloosheid onnodig hoog oploopt, moet het overheidsbeleid aansluiten bij het 'hamsteren' van personeel door werk- en opdrachtgevers, met drie concrete...

Public organizations often face numerous barriers when it comes to adopting and using social media to communicate and engage with the broader public. This research aims to better understand how barriers to social media adoption can be tackled by zooming in on one specific type of organization: the police. Our research answers the following...

Structures are subjected to cyclic loads that can vary in direction and magnitude, causing constant amplitude mode I simulations to be too simplistic. This study presents a new approach for fatigue crack propagation in ductile materials that can capture mixed-mode loading and overloading. The extended finite element method is used to deal with...

Changing an established way of working can be a real headache. This is particularly true if there are high stakes involved, e.g., when changing the development process for complex systems. New design methods, such as model-based engineering (MBE) using domain-specific languages (DSLs) promise significant gains, such as cost reductions and...

Experiences from recent conflicts show the strong need for smart sensor suites comprising different multi-spectral imaging sensors as core elements as well as additional non-imaging sensors. Smart sensor suites should be part of a smart sensor network - A network of sensors, databases, evaluation stations and user terminals. Its goal is to...

Localised buckles can occur in crasheswhen compressive stresses are dominant. However, due to their local appearance, they might be overlooked by a finite element analysis, meaning that local failure due to bucklingwill not be predicted. This could, for example, be catastrophic in the case of the crushing of a fuel tank or the impact on a ship...

Depending on the state of stress, material can fait in a number of different modes during a collision. Three modes are identified here as material separation in the absence of necking, material separation after the onset of necking, and localized buckling/wrinkling. Through a series of case studies, the states of stress present in a collision...

In this day and age, there exists an increasing need for systems and architectures able to process spatio-temporal data in a timely way. As a result, this paper presents CEP-traj, a novel middleware to ease the development of real-time trajectory-based services based on the Complex Event Processing (CEP) paradigm. By means of an event-based...

One of the most previous conservation treatments for plant specimen in herbarium collections was mercuric chloride (HgCl2). However, due time HgCl2 may decompose and it may cause (metallic) mercury (Hg) emission. Hg vapour in indoor air should be avoided as mercury poisoning can already occur at levels of 6 μg/m3. Both field and laboratory...

The present invention relates to a method for producing a substrate with at least one covered via that electrically and preferably also thermally connects a first substrate side with an opposite second substrate side. The processing involves forming a trench on a the first substrate side remains and covering the trench with a permanent layer on...
