This study deals with ductile fracture prediction of a marine steel using new damage functions. The stress triaxiality and Lode angle are known to be governing parameters on the ductile fracture. Recent research has reported that loading path is also one of the important parameters. A three-dimensional fracture strain surface for EH36 steel was...

In this paper, identification of energy dissipation in the joints of a lab-scale structure is accomplished. The identification is carried out by means of an energy flow analysis and experimental data. The devised procedure enables to formulate an energy balance in the vicinity of the joints to obtain local energy dissipation. In this paper, a...

De vraag naar grondstoffen voor de bouwopgaaf, de grote hoeveelheid (sloop)afval uit de bouw en de impact van de bouwsector op broeikasgasemissies vragen om een efficiënte en duurzame manier omgang met bouwmaterialen. Het Rijksbrede programma circulaire economie was voor TNO aanleiding om in deze publicatie te laten zien hoe wij aankijken tegen...

Backside ventilation is one of the most common passive cooling methods of PV modules in the built environment, but might be under constraint when integrating PV in the building envelope. To investigate the short and long term effect of backside ventilation on Building Integrated PV (BIPV) performance and lifespan, a comparative BIPV field test...

In the small scale LNG infrastructure, composite materials are scarcely employed. Potentially, cost effective solutions for LNG applications could be developed thanks to the advantages of composite materials over metals such as weight savings, design flexibility and recyclability. The research presented in this paper focuses on the mechanical...

In recent years, the use of computational fluid dynamics (CFD) to evaluate flow fields has become more popular in various branches of industry. In building design, there is a similar trend towards the increasing use of CFD. There are several guidelines for CFD analysis of flows in the urban environment, e.g. [1-4]. For assessment of wind speed...

A long-term monitoring project, with 12 months of continuous operation time, is described where the sound sources within a large industrial area as well as the sound levels in the nearby residential area are measured. The sources in the industrial area may give rise to complaints from the neighboring residential areas, at several kilometers...

Building Integrated PV (BIPV) is considered as a key development for successful deployment of PV in the built environment. However, the effect of PV integration on environmental impact is not fully understood. In this study a single indicator for environmental impact assessment of BIPV is investigated in the Netherlands. A BIPV rooftop with 24...

It is sometimes necessary to find the toughness of existing structures without damaging them. Examples of this scenario include situations in which the material is suspected of being brittle or service life extensions. However, fracture testing is inherently destructive. Removing material for Charpy or Crack Tip Opening Displacement (CTOD)...

Instantaneous insight into the structural damage sustained by a ship running aground, can be of great aid in the decision making following such a disaster. It should be possible to distil the extent of structural damage from acceleration measurement data of the entire vessel. Such measurements could possibly even be done using a simple...

The last decade has seen a growing interest in cohesive zone models for fatigue applications. These cohesive zone models often suffer from a lack of generality and applying them typically requires calibrating a large number of model-specific parameters. To improve on these issues a new method has been proposed in this paper based on the Thick...

An investigation is presented to determine the wind loads on external solar blinds on two 60 m high towers. This investigation was performed some years after the construction of the towers, with the sun blinds in place. A combination of wind tunnel tests and full scale measurements was done. The shape of the towers, and the unique design of the...

Fatigue is one of the main design drivers for offshore wind substructures. Using Fracture Mechanics methods, load sequence effects such as crack growth retardation due to large load peaks can be included in the fatigue damage estimation. Due to the sequence dependency, a method is required that represents the sequences of loads in the design or...

In this paper simplified expressions for assessing fundamental frequency and modal damping of high-rise buildings taking into account the soil-structure interaction (SSI) are proposed. To this end, several steps have been followed. First, a 3DoF model is formulated making use of dimensionless parameters. Second, the 3DoF model is simplified into...

Wind loads are responsible for a large amount of damage to greenhouses, and are therefore an important factor in the structural design of greenhouses. Previous wind load studies on greenhouses [1-8], have only investigated wind loads on the first 9 roof spans. However, most greenhouses are much larger than 10 roof spans. For these larger...

Voor de bevestiging van dakbedekkingen worden in Nederland specifieke rekenregels gegeven via NEN 6707 en NPR 6708. Dit betreft zowel de regels voor de bepaling van de windbelasting als methodes om de sterkte te bepalen. Deze regels zijn voor zowel hellende als platte daken afgeleid uit resultaten van onderzoek dat in de laatste decennia in...

Traditionally, a failure strain criterion is used in crash simulations in the maritime and offshore industry. More sophisticated methods for multi-axial stress states are based on the Forming Limit Diagram and the Fracture Forming Limit Diagram (FFLD). The diagrams are derived for the steel sheet forming industry, such as car parts. Few tests...

The wind loads on solar energy systems are crucial for the engineering of the panels, substructure and fixings. There is a demand for aesthetically more acceptable solutions such as frameless solar systems. For these frameless systems, the wind loads are carried by the panels themselves. Combined with the increase in the size of photovoltaic (PV...

The local approach to modelling ductile tearing is a useful technique to give insight into fracture mechanics. However, applications of the local approach have been stymied by the high cost of finding the parameters that characterize it because of the number of specimens and expensive post-processing that the testing requires. In this paper, a...

Offshore areas are rough and high energy areas. Therefore, offshore constructions are prone to high technical risks. This chapter elaborates on the technical risks of corrosion and biofouling and technical risks through mechanical force. The expected lifetime of an offshore structure is to a great extent determined by the risk of failures...
