'Universal'microstructural patterns in cortical and trabecular, extracellular and extravascular bone materials: micromechanics-based prediction of anisotropic elasticity

A Fritsch, C Hellmich - Journal of Theoretical Biology, 2007 - Elsevier
Bone materials are characterized by an astonishing variability and diversity. Still, because of
'architectural constraints' due to once chosen material constituents and their physical …

Micromechanical modeling of solid-type and plate-type deformation patterns within softwood materials. A review and an improved approach

K Hofstetter, C Hellmich, J Eberhardsteiner - 2007 - degruyter.com
Wood exhibits a highly diverse microstructure. It appears as a solid-type composite material
at a length scale of some micrometers, while it resembles an assembly of plate-like elements …

Upscaling quasi-brittle strength of cement paste and mortar: A multi-scale engineering mechanics model

B Pichler, C Hellmich - Cement and Concrete Research, 2011 - Elsevier
It is well known from experiments that the uniaxial compressive strength of cementitious
materials depends linearly on the degree of hydration, once a critical hydration degree has …

Development and experimental validation of a continuum micromechanics model for the elasticity of wood

K Hofstetter, C Hellmich, J Eberhardsteiner - European Journal of …, 2005 - Elsevier
This contribution covers the development and validation of a microelastic model for wood,
based on a four-step homogenization scheme. At a length scale of several tens of …

Mineral–collagen interactions in elasticity of bone ultrastructure–a continuum micromechanics approach

C Hellmich, JF Barthélémy, L Dormieux - European Journal of Mechanics-A …, 2004 - Elsevier
The organization of the elementary components within the ultrastructure of mineralized
tissues (bone and mineralized tendons) has provoked some controversy; especially with …

CD38-driven mitochondrial trafficking promotes bioenergetic plasticity in multiple myeloma

…, RE Piddock, JJ Mistry, L Zaitseva, C Hellmich… - Cancer Research, 2019 - AACR
Metabolic adjustments are necessary for the initiation, proliferation, and spread of cancer
cells. Although mitochondria have been shown to move to cancer cells from their …

Ductile sliding between mineral crystals followed by rupture of collagen crosslinks: experimentally supported micromechanical explanation of bone strength

A Fritsch, C Hellmich, L Dormieux - Journal of theoretical biology, 2009 - Elsevier
There is an ongoing discussion on how bone strength could be explained from its internal
structure and composition. Reviewing recent experimental and molecular dynamics studies …

Impact of rocks onto gravel design and evaluation of experiments

B Pichler, C Hellmich, HA Mang - International Journal of Impact …, 2005 - Elsevier
Layers of gravel represent an energy-absorbing system for structures subjected to rockfall.
To support the design of such structures, relations between the penetration depth, the impact …

Stable pitting corrosion of stainless steel as diffusion-controlled dissolution process with a sharp moving electrode boundary

S Scheiner, C Hellmich - Corrosion science, 2007 - Elsevier
This paper is devoted to explanation and prediction of pit propagation or stable pit growth,
governed by ion transport properties in electrolytic solutions. Therefore, we vigorously derive …

Spherical and acicular representation of hydrates in a micromechanical model for cement paste: prediction of early-age elasticity and strength

B Pichler, C Hellmich, J Eberhardsteiner - Acta Mechanica, 2009 - Springer
Early-age stiffness and strength evolution of cement paste is studied in the framework of
continuum micromechanics. Based on the self-consistent scheme, elastic and strength …
