Swelling-induced pattern transformations of periodic hydrogels -- from the wrinkling of internal surfaces to the buckling of thin films
Elten Polukhov, Laura Pytel, Marc-Andre Keip
We investigate pattern transformations of periodic hydrogel systems that are triggered by swelling-induced structural instabilities. The types of microstructures considered in the…
Transient stability analysis of composite hydrogel structures based on a minimization-type variational formulation
Siddharth Sriram, Elten Polukhov, Marc-Andre Keip
We employ a canonical variational framework for the predictive characterization of structural instabilities that develop during the diffusion-driven transient swelling of hydrogels…
A variational minimization formulation for hydraulically induced fracturing in elastic-plastic solids
Daniel Kienle, Marc-Andre Keip
A variational modeling framework for hydraulically induced fracturing of elastic-plastic solids is developed in the present work. The developed variational structure provides a glo…
A Variational Framework for the Thermomechanics of Gradient-Extended Dissipative Solids -- with Applications to Diffusion, Damage and Plasticity
Stephan Teichtmeister, Marc-Andre Keip
The paper presents a versatile framework for solids which undergo nonisothermal processes with irreversibly changing microstructure at large strains. It outlines rate-type and incr…
