Borgart, A. (author)
Shell structures can be either calculated with complex mathematics and differential geometry, or with the help of finite element method (FEM) software. Neither method gives the designer sufficient insight about the behaviour of the shell in the early design stage. The first method is for most designers too complex, it requires proficiency in at...

Balzani, Daniel (author), Heinlein, A. (author), Klawonn, Axel (author), Knepper, Jascha (author), Nurani Ramesh, Sharan (author), Rheinbach, Oliver (author), Saßmannshausen, Lea (author), Uhlmann, Klemens (author)
A computational framework is presented to numerically simulate the effects of antihypertensive drugs, in particular calcium channel blockers, on the mechanical response of arterial walls. A stretch-dependent smooth muscle model by Uhlmann and Balzani is modified to describe the interaction of pharmacological drugs and the inhibition of smooth...

The method of Macaulay utilizes singularity functions to describe discontinuous forces acting on beam structures. This method has been extended to determine internal forces and deformation properties, where the beam is inclined at a certain angle or curved.

Jankie, julia (author)
Macaulay's method utilizes singularity functions to describe discontinue forces acting on beam structures. This method has been extended to determine internal forces and influence lines, making use of a single expression. The method can be applied to analyze all possible scenarios for both one-dimensional and two-dimensional constructions.

van der Wulp, Justus (author)
Macaulay's method, which makes use of singularity functions to describe external forces on beam structures, is extended for two-dimensional structures. Furthermore an extension on the method of Macaulay is described for singularities in the rotation and displacement field of the structures, based on the article of Falsone, G. (2002), ‘’The Use...

The current owners of the Scheveningen Pier are starting to head into the second phase of their exploitation plan, which is to replace the current pier. This new pier is larger than the current pier and can exploit at a higher level. This thesis creates a design for a new Scheveningen Pier. A design method is used, which combines the engineering...

Chokshi, Shasan (author)
This thesis aims to explore various possibilities in grid-structures by introducing atypical line geometries and examine its feasibility in a built environment. The proposition is derived from the larger purpose of adapting native design characteristics in modern built environment. Focusing on the Asian context, one of the essential...

Yu, C. (author)
It is difficult to accurately predict the strength of masonry and concrete structures. The most widely used method for simulating their behaviour is finite element analysis with the Newton-Raphson method and arch length control. However, the Newton-Raphson method can diverge and not produce a result, for example in bifurcations or during snap...

De Lazzari, Elena (author)
Generalized finite element methods have proved a great potential in the mesh-independent modeling of both weak and strong discontinuities, such as the ones encountered when treating materials with inclusions or cracks. By removing the constraint of a conforming mesh, more freedom is offered to modeling exact geometries by means of splines....

Large discontinuities in material properties, such as those encountered in composite materials, lead to ill-conditioned systems of linear equations. These discontinuities give rise to small eigenvalues that may negatively affect the convergence of iterative solution methods such as the preconditioned conjugate gradient method. This paper...

Many applications in computational science and engineering concern composite materials, which are characterized by large discontinuities in the material properties. Such applications require fine-scale finite-element meshes, which lead to large linear systems that are challenging to solve with current direct and iterative solutions algorithms....

Simulations with composite materials often involve large jumps in the coefficients of the underlying stiffness matrix. These jumps can introduce unfavorable eigenvalues in the spectrum of the stiffness matrix. We show that the rigid body modes; the translations and rotations, of the disjunct rigid bodies in the composite material correspond to...

The demand for large FE meshes increases as parallel computing becomes the standard in FE simulations. Direct and iterative solution methods are used to solve the resulting linear systems. Many applications concern composite materials, which are characterized by large discontinuities in the material properties. An example of such a material is...
