Theorie und Numerik einer oberflächenorientierten Schalenformulierung
… of textile reinforced concrete to strengthen a shell structure. The main focus lies on both the geometrical and physical non-linear three-dimensional shell formulation and on its transfer into an efficient finite element. The distinctive feature of the presented shell formulation is its …

Dynamic simulation of heart mitral valve with transversely isotropic material model
… tissue. First, a mixed pressure-displacement formulation is used to implement the constitutive material behavior with general 3D elements. Second, a shell is formulated that incorporates the 3D material behavior by use of a local plane stress iteration method. Both of these works are based on …

Analytic progress in open string field theory
… string fields, and it is thus a manifestly off-shell formulation of open string theory. The solutions to the equation of motion of open string field theory are expected to describe consistent classical open string backgrounds. In this thesis, I present a number of analytic results in bosonic …

Shell finite elements, with applications in biomechanics
This thesis gives a detailed presentation of a formulation for thin shells, and its finite element approximation, with the goal of modelling soft, thin biological tissues. The rigorous but complex theory due to Simo and Fox (1986) is presented in an accessible manner, with detailed derivations …
