Kovacs-like memory effect in strain stiffening collagen networks

Published on 2026-06-10 by Abhishek Ghadai, Maitri Mandal and Sayantan Majumdar @IOP SCIENCE

Abstract: Materials driven far from equilibrium can encode memories of past deformations through long-lived structural reorganizations. Such memory effects-reflecting parameters such as deformation direction, magnitude, and duration have been widely explored in soft amorphous solids. Here, we report a Kovacs-like memory effect manifested as a non-monotonic stress relaxation in vitro biopolymer networks formed by type-I collagen, an essential component of the mammalian extracellular matrix. Using shear rhe[...]


Our summary: The study identifies a Kovacs-like memory effect in type-I collagen networks. This effect is linked to non-monotonic stress relaxation during nonlinear strain-stiffening. The findings reveal a correlation between memory response and negative normal stresses in biopolymer networks.
