Orthotropic Viscoelastic Creep in Cellular Scaffolds
Alessia Ferrara, Falk K. Wittel
Recent measurements of Norway spruce have revealed stress-state-dependent normalized creep behavior, highlighting a gap in our fundamental understanding. This study examines whethe…
Resolving Discrepancies in Wood Micromechanics: Strain-Mapped Compression of Tracheid Wall Micropillars
Júlio O. Amando de Barros, Jakob Schwiedrzik, Falk K. Wittel
Wood's increasing role as a structural resource in sustainable materials selection demands accurate characterization of its mechanical behavior. Its performance arises from a hiera…
Morphologic Evolution in Simulated Wood Densification
Alessia Ferrara, Júlio O. Amando de Barros, Sophie Marie Koch +1
This study investigates the radial densification of spruce wood using explicit Finite Element Method simulations, focusing on the effects of various densification protocols. These…
Comprehensive creep compliance characterization of orthotropic materials using a cost-effective automated system
Jonas M. Maas, Falk K. Wittel
Determining the creep compliances of orthotropic composite materials requires experiments in at least three different uniaxial and biaxial loading directions. Up to date, data resp…
A Unifying Model for the Rheological Behavior of Hygro-responsive Materials
Júlio Amando de Barros, Falk Wittel
Hygro-responsive materials exhibit a complex structure-to-property relationship. The interactions of water within these materials under varying hygric and mechanical loads play a c…
Damage Preserving Transformation for Materials with Microstructure
Philip P. Müller, Falk K. Wittel, David S. Kammer
The failure of heterogeneous materials with microstructures is a complex process of damage nucleation, growth and localisation. This process spans multiple length scales and is cha…
