Simulating the Mechanically Induced Reaction of Energetic Materials: A Non-Linear Simulation of Finite Element Analysis

Munition articles may be sensitive to case-crushing loading. This is a potential safety hazard since it may lead to accidental detonation. A better understanding of the mechanism causing the munition articles to react can help improve safety. A finite element model combined with post-processing is used to model a Steven test. This thesis...

Blast response of Glass Facades: Retrofit for blast effect mitigation in the event of a terrorist bombing attack

The number of terrorist attacks on public places has substantially grown over the past two decades. More than half of these attacks were bombings. Past bombing events have shown that 45% of the injuries is caused by glass breakage. . The building engineering practice could help reducing the consequences, by retrofitting glass facades to mitigate...

Extension of the Use of a Single Degree of Freedom Model for Non-Uniform Load Distributions

In this research the translation of non-uniform load distributions to equivalent uniform load distributions has been investigated. The equivalent uniform load can be used as input for a single degree of freedom model to compute vulnerability analyses in which hundreds of scenarios need to be analysed.

Numerical Erosion in Continuum Damage Mechanics

Implementing numerical erosion in damage models predicting failure in concrete subject to impact loading.

Nonlocal Damage Models for Concrete

An understanding of response of concrete structures to impact loading is of interest to the Explosions, Ballistics and Protection department of TNO. Numerical simulations conducted to study this response require very small elements to capture the shockwave propagation and the material response which were found to be mesh dependent. The goal of...

Blast-resistant building design: Methods and solutions for the blast-resistant design of buildings subjected to an LPG tank truck explosion

Because of the wish for, and the necessity of the multiple use of space the amount of tunnels and buildings in close proximity of roads are increasing. Meanwhile the number of transports of dangerous goods is also increasing. Therefore it would be desirable to have a highway network which is fully accessible for the transport of dangerous goods....

Constructieve samenhang van prefab gebouwconstructies na een gasexplosie: Onderzoek naar maatregelen om constructieve samenhang te waarborgen in relatie tot de Europese Norm

In de praktijk worden steeds meer gebouwen vervaardigd uit geprefabriceerde betonelementen. Deze elementen worden in de fabriek gemaakt waarna ze worden getransporteerd naar de bouwplaats. Op de bouwplaats worden deze onderdelen aan elkaar bevestigd. Deze werkwijze bespaart tijd in de uitvoeringsfase ten opzichte van traditionele betonbouw ...
