Fluctuation phenomena in crystal plasticity - a continuum model [PDF]
, 2005 On microscopic and mesoscopic scales, plastic flow of crystals is characterized by large intrinsic fluctuations. Deformation by crystallographic slip occurs in a sequence of intermittent bursts ('slip avalanches') with power-law size distribution. In the

FEBS Open Bio, EarlyView.We found that during chemotherapy‐induced alopecia (CIA), Sonic hedgehog (Shh) expression significantly decreased in hair follicle Shh+ cells, whereas the Janus‐activated kinase/signal transducer and activator of transcription 1 (JAK/STAT1) signaling pathway was markedly activated.

Nanoscale Strain-Hardening of Keratin Fibres
PLoS ONE, 2012 Mammalian appendages such as hair, quill and wool have a unique structure composed of a cuticle, a cortex and a medulla. The cortex, responsible for the mechanical properties of the fibers, is an assemblage of spindle-shaped keratinized cells bound together by a lipid/protein sandwich called the cell membrane complex. Each cell is itself an assembly of

A non-linear hardening model based on two coupled internal hardening variables: formulation and implementation [PDF]
, 2005 An elasto-plasticity model with coupled hardening variables of strain type is presented. In the theoretical framework of generalized associativity, the formulation of this model is based on the introduction of two hardening variables with a coupled ...

Multi-stage strain-hardening behavior of dual-phase steels: A review
Journal of Materials Research and TechnologyRegardless of the abundant studies that have been published on various characteristics of dual-phase (DP) steels, a comprehensive review paper on the strain-hardening behavior of such materials is still lacking.

A material model for warm forming of aluminium sheet [PDF]
, 2003 A material model has been developed to simulate the warm forming of Al–Mg\ud sheet. Both the hardening behaviour, including temperature and strain rate effects, and the\ud biaxial stress–strain response of the sheet are considered.

On stress resultant plasticity and viscoplasticity for metal plates [PDF]
, 2008 In this work we derive elastoplastic and elastoviscoplastic finite element formulations for stress resultant bending analysis of thin metal plates. The principle of maximum plastic dissipation is used to obtain the ingredients of the small strain stress ...

FEBS Open Bio, EarlyView.dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Plastic instability in complex strain paths predicted by advanced constitutive equations [PDF]
The present paper aims at predicting plastic instabilities under complex loading histories using an advanced sheet metal forming limit model. The onset of localized necking is computed using the Marciniak-Kuczinslcy (MK) analysis [I] with a physically ...
