Open AccessA note concerning some aspects for application of a thermodynamic extremal principle (TEP) for continua
A matter of fact is that extremal principles have been introduced in mechanics in more (Euler, Lagrange) or less (Hamilton) than 200 years ago. One may also observe an impact of thermodynamic extremal principl...

Open AccessStrain and interface energy of ellipsoidal inclusions subjected to volumetric eigenstrains: shape factors
Thermodynamic modeling of the development of non-spherical inclusions as precipitates in alloys is an important topic in computational materials science. The precipitates may have markedly different properties...

Open AccessStress–strain analysis of the antiplane shear problem for an infinite cylindrical inclusion with eigenstrain: an addendum to Arch. Appl. Mech. 2018
As outlined in the previous paper, an eigenstrain state due to an interstitial atom, acting as misfitting inclusion in the crystal lattice, may interact with a load stress state and/or a stress state due to a ...

Open AccessElastic stress–strain analysis of an infinite cylindrical inclusion with eigenstrain
The ensemble of interstitial atoms as C attracted to a dislocation is well established as “Cottrell cloud” phenomenon. The deposition of the interstitial atoms in octahedral or tetrahedral positions in a bcc l...

A thermodynamic study of voiding phenomena in Cu–Cu thermo-compression wafer bonding
The influence of wafer bonding and post-bond annealing conditions on the (cavity) void size and distribution was investigated theoretically and verified experimentally. Based on Cu–Cu thermo-compression bondin...

Variational Concepts with Applications to Microstructural Evolution
In systems at elevated temperature the development of the microstructure of a material is controlled by diffusional and interface migration processes. As first step the description of the microstructure is red...

Utilization of the thermodynamic extremal principle for modelling in material science
Modelling represents an important tool in the material science. It can simulate the technological steps as well as predict the material properties. A lot of technological steps are performed as well as several...
