BioResources, 2014 Uniaxial compression tests in the grain (longitudinal) direction of solid wood were conducted using specimens of Sitka spruce and Japanese birch. The nonlinear stress-strain behavior was analyzed using plasticity theory, which is typically applied to ...

Plastic Buckling Paradox: An Updated Review
Frontiers in Built Environment, 2020 It is widely accepted that the flow theory of plasticity significantly overestimates buckling stresses and strains and, in some cases, fails to predict buckling at all, while the deformation theory, which lacks physical rigor compared to the flow theory,

Self-Organization of Microcircuits in Networks of Spiking Neurons with Plastic Synapses. [PDF]
PLoS Computational Biology, 2015 The synaptic connectivity of cortical networks features an overrepresentation of certain wiring motifs compared to simple random-network models. This structure is shaped, in part, by synaptic plasticity that promotes or suppresses connections between ...

Surface plasticity: theory and computation
Computational Mechanics, 2017 Surfaces of solids behave differently from the bulk due to different atomic rearrangements and processes such as oxidation or aging. Such behavior can become markedly dominant at the nanoscale due to the large ratio of surface area to bulk volume.

Familiarization: A theory of repetition suppression predicts interference between overlapping cortical representations. [PDF]
PLoS ONE, 2017 Repetition suppression refers to a reduction in the cortical response to a novel stimulus that results from repeated presentation of the stimulus. We demonstrate repetition suppression in a well established computational model of cortical plasticity ...

Contact of Rough Surfaces: An Incremental Model Accounting for Strain Gradient Plasticity
Lubricants, 2023 In the contact of rough surfaces, most contact patches are at the scale of micrometers, and thus, their contact deformation can be dominated by the size-dependent plasticity. In this paper, we propose a new strategy to analyze the role of strain gradient

Multiscale Theory of Dislocation Plasticity
CrystalsMotion of dislocations is a common mechanism of plasticity in many materials. Dislocation-mediated deformation is essentially an inhomogeneous process, which is manifest in the formation of slip lines and complicated cell wall structures.

MODELING THE PLASTIC DEFORMATION STATE OF THE CONTACT SURFACE DURING FRICTION
Eurasian Physical Technical JournalThe mechanics of contact destruction of compounds during friction under conditions of complex thermodynamic loading was researched. The possibility of a mathematical description of complex damage to friction units and wear intensity is shown, taking ...
