Identification of mine blast interaction pressure on excited plates: Using transient adjoint optimization for solving the inverse problems

Mines and improvised explosive devices are the cause of many mortalities of vehicle occupants. Both experimental and numerical research in this field aims to improve the safety of military vehicles. TNO has advanced Finite Element (FE) models to simulate such events. The numerical research is done to better understand mine blasts. Another aim is...

Steering towards Stiffness: A preliminary analysis method for local deformations in a yacht structure caused by wave-induced loads

The superyacht industry faces an increasing trend of larger dimensions, more open spaces, larger hull openings and more exotic shapes. This puts more effort on the structural design and especially for superyacht longitudinal stiffness is important, since the luxurious interior and delicate systems installed in a superyachts are not allowed to...

An engineering perspective to the virtual element method and its interplay with the standard finite element method

In this manuscript we thoroughly study the behavior of the virtual element method (VEM) in the context of two-dimensional linear elasticity problems for an engineering audience versed in standard FEM. Through detailed convergence studies we show the accuracy and the convergence rates recovered by VEM, and we compare them to those obtained by...

Development of a Reliable and Efficient 3D Calculation Model of a High-Rise Building Under Seismic Loading

This thesis research focusses on the development of a reliable and efficient 3D calculation model of an existing high-rise, reinforced concrete building in the Groningen area, in order to analyse the dynamic behaviour of the existing and subsequently retrofitted main bearing structure of this high-rise building. The assessment of the existing...
