Plastic cross sections of B16 cell lamellipodia showed a constant thickness across their breadth that varied between 70 and 100 nm (not shown).
A generally applicable numerical method for the evaluation of plastic cross-section resistance is presented.
The method extends the "hole in the web" approach used by AS 2327.1 and the European Standard Eurocode 4 for the plastic cross-section analysis of non-compact webs (EC4 Class 3) to cover the elastic cross-section analysis of slender webs (EC4 Class 4).
When adopting the theory of plastic zones instead of the theory of plastic hinges, partially plastic cross-sections can also be considered.
Here, to estimate and compare the levels of axonal loss with the expansion of glial coverage and axonal degeneration in DBA/2J nerves, we combined semiautomatic axon counts with threshold-based segmentation of total glial/scar areas and degenerative axonal profiles in plastic cross-sections.
Nerves from 10-month-old Cx3cr1GFP/+ DBA/2J mice including the retro-orbital, myelinated segment (1-1.5 mm post-lamina), were prepared as 1-µm-thick plastic cross-sections, and stained with a modified paraphenylenediamine (PPD) protocol and Toluidine Blue (Anderson et al., 2005; Calkins et al., 2005; Inman et al., 2006; Sappington et al., 2003).
In the design of continuous steel concrete composite girders, cross section plastic resistance can be exploited in the sagging regions, where the compressed flange of the steel beam is connected to the reinforced concrete slab.
In a combined design approach, which uses the cross section plastic resistance in the sagging regions and the cross section elastic resistance in the hogging regions, the design must satisfy the condition that the sagging plastic moment can develop while the hogging bending moment remains below the elastic limit.
This revolving, continuous plastic working of an oval cross section between the two rolls creates tensile stresses in the long axes of the oval, which rupture the centre and create a cavity.
Profile extrusion is a manufacturing process used for continuous plastic profiles with a fixed cross section.
Energy dissipation per cycle in members undergoing lateral-torsional buckling remained constant through large flexural rotations because the failure mechanism involved mid-span cross-section rigid body motion without plastic deformations spreading across the cross section.
