Self-induced marginality in plastically deformed crystals
Oguz Umut Salman, Aylin Ahadi, Lev Truskinovsky
Quasi-brittle plastic yielding is a salient feature of well-annealed glassy materials. Here we show that the same behavior is characteristic of perfect crystals after they experien…
Micro-displacement tensor
Giuseppe Zurlo, Lev Truskinovsky
We propose an extended kinematics of nominally elastic continuum solids allowing one to describe their mechanical interaction with micro-scale loading devices. The main new ingredi…
Inertia-induced power-law scaling in martensites
Oğuz Umut Salman, Alphonse Finel, Lev Truskinovsky
Martensites subjected to quasistatic deformation are known to exhibit power law distributed acoustic emission in a broad range of scales, however, the origin of the observed scalin…
Active chemo-mechanical solitons
Lev Truskinovsky, Giuseppe Zurlo
In many biological systems localized mechanical information is transmitted by mechanically neutral chemical signals. Typical examples include contraction waves in acto-myosin corte…
Nonlinear stability in a free boundary model of active locomotion
Leonid Berlyand, C. Alex Safsten, Lev Truskinovsky
Contraction-driven self-propulsion of a large class of living cells can be modeled by a Keller-Segel system with free boundaries. The ensuing "active" system, exhibiting both dissi…
Slip-dominated structural transitions
Kanka Ghosh, Oguz Umut Salman, Sylvain Queyreau +1
We use molecular dynamics to show that plastic slip is a crucial component of the transformation mechanism of a square-to-triangular structural transition. The latter is a stylized…
Optimal crawling: from mechanical to chemical actuation
Pierre Recho, Lev Truskinovsky
Taking inspiration from the crawling motion of biological cells on a substrate, we consider a physical model of self-propulsion where the spatio-temporal driving can involve both,…
Active drive towards elastic spinodals
Ayan Roychowdhury, Madan Rao, Lev Truskinovsky
Active matter, exemplified by adaptive living materials such as the actomyosin cytoskeleton, can navigate material parameter space dynamically, leading to unconventional mechanical…
Active gel segment behaving as an active particle
Pierre Recho, Thibaut Putelat, Lev Truskinovsky
We reduce a one-dimensional model of an active segment (AS), which is used, for instance, in the description of contraction driven cell motility on tracks, to a zero-dimensional mo…
Landau theory of bending-to-stretching transition
O. U. Salman, G. Vitale, L. Truskinovsky
Transition from bending-dominated to stretching-dominated elastic response in semi-flexible fibrous networks plays an important role in the mechanical behavior of cells and tissues…
Colliding cells: when active segments behave as active particles
Pierre Recho, Thibaut Putelat, Lev Truskinovsky
Quantifying the outcomes of cells collisions is a crucial step in building the foundations of a kinetic theory of living matter. Here, we develop a mechanical theory of such collis…
