We study a crystal with a motionless crack exhibiting the transformational process zone at its tip within the field-theoretical approach. The latter enables us to describe the transformation toughness phenomenon and relate it to the solid's location

The morphological transformation of the process zone at the tip of a propagating crack occurs with the increase of the crack velocity. The zone configuration changes its shape from concave to convex, dropletlike form. The latter exhibits a metastable

Stress concentration at a crack tip engenders a process zone, a small domain containing a phase, different from that in the bulk of the solid. We demonstrate that this zone at the tip of a propagating crack exhibits a morphological transformation wit

Stress concentration at a crack tip generates a solid structural transformation in its vicinity, the process zone. We argue that its formation represents a local phase transition described by a multicomponent order parameter. We derive a system of eq

The crack tip process zone is regarded as a region where the solid physical properties are altered due to high stress. They are controlled by the solid degrees of freedom existing within the zone and vanishing outside, and can be divided into two cla

A process zone containing a new phase often forms at the tip of a crack in a quasi-brittle solid. We study such a zone engendered by the propagating crack. We show that depending on the crack speed, V , this zone has two distinct configurations. If t

We describe the enforced unbinding of a bead from i) a supported membrane, and ii) a cell surface. The force necessary to unbind the bead is obtained and is shown to be within the range accessible in micromechanical experiments.

We establish a model of cell-tissue interaction consisting of vesicles carrying lipopolymers (to mimic the glycocalix) and mobile specific ligands of the blood platelet integrin αIIbβ3 covering the substrate. We find the phase diagram with a first-

We report a theoretical calculation of the elasticity of the peptidoglycan network, the only stress-bearing part of rod-shaped Gram-negative eubacteria. The peptidoglycan network consists of elastic peptides and inextensible glycan strands, and it ha
