A Romantic Genius? The Experience of Knowledge that Shaped Werner Heisenberg's Scientific Persona
Berichte zur Wissenschaftsgeschichte, Volume 48, Issue 1-2, Page 72-90, August 2025.In 1976, the year that Werner Heisenberg passed away, Armin Hermann published a short biography, titled Werner Heisenberg in Selbstzeugnissen und Bilddokumenten. Since then, historians and biographers have offered their accounts on Heisenberg's life and his contributions to modern physics. Many of these biographies present Heisenberg as a genius.

International Journal for Numerical Methods in Engineering, Volume 125, Issue 24, 30 December 2024.Abstract Mixed Finite Elements (FEs) with assumed stresses and displacements provide many advantages in analysing shell structures. They ensure good results for coarse meshes and provide an accurate representation of the stress field. The shell FEs within the family designated by the acronym Mixed Isostatic Self‐equilibrated Stresses (MISS) have ...

On the systematic construction of trial functions for hybrid Trefftz shell elements
Computer Assisted Methods in Engineering and Science, 2023 In this paper the possibility of applying the Trefftz-method to thick and thin shells is discussed. A mixed variational formulation is used in which the assumed strain and stress functions are derived from the three-dimensional solution representation ...

Variational Integrators and Fluid‐Structure‐Interaction at Low Reynolds‐Number
Proceedings in Applied Mathematics and Mechanics, Volume 19, Issue 1, November 2019., 2019 Abstract For the special case of incompressible and highly viscous fluids, the interaction with a rigid body can be collected in a damping matrix, relating the velocities and angular velocities of the body with the fluid force and torque. This damping matrix (a.k.a. viscous resistance matrix) depends exclusively on the geometry and needs to be computed

Trefftz methods for plane piezoelectricity
Computer Assisted Methods in Engineering and Science, 2023 Starting from the governing equations, the general solution and the complete solution set for plane piezoelectricity are derived in this paper. Subsequently, the Trefftz collocation method (TCM) is formulated.

Solution of 2D non-homogenous wave equation by using polywave functions
Computer Assisted Methods in Engineering and Science, 2017 The paper presents a specific technique of solving the non-homogenous wave equation with the use of Trefftz functions for the wave equation. The solution was presented as a sum of a general integral and a particular integral.

Folded-plate structures with openings - analysis and optimization
Computer Assisted Methods in Engineering and Science, 2023 This paper is a continuation and development of the dissertation [1]. Complex folded-plate structures with holes are analyzed using the Trefftz-type finite elements, which appears very effective. The shape functions of these elements (Trefftz functions)

Hybrid‐Trefftz finite element method for heat conduction in nonlinear functionally graded materials
Engineering Computations, 2011 PurposeThe purpose of this paper is to develop a hybrid‐Trefftz (HT) finite element model (FEM) for simulating heat conduction in nonlinear functionally graded materials (FGMs) which can effectively handle continuously varying properties within an element.Design/methodology/approachIn the proposed model, a T‐complete set of homogeneous solutions is ...
