An asymptotic model is constructed to describe the bending of thin sheets, or plates, viscoplastic fluid described by Herschel–Bulkley constitutive law, which incorporates von Mises yield condition and a nonlinear viscous stress. The reduces number previous ones from plasticity theory mechanics in various limits. It characterized criterion proposed Ilyushin compactly combines effect moment in-p...

LactoSorb fixation plates are made of a bioabsorbable polymer (82% poly-L-lactic acid and 18% polyglycolic acid), and the strength is not inferior to titanium plates. LactoSorb has been used in the fields of pediatric neurosurgery and facial plastic surgery. Cranial fixation in craniotomy is mostly performed using titanium plates and clamps, but there are issues with esthetics and artifacts on ...

OBJECTIVE To review the biomechanical principles that guide fracture fixation with plates and screws; specifically to compare and contrast the function and roles of conventional unlocked plates to locked plates in fracture fixation. We review basic plate and screw function, discuss the design rationale for the new implants, and examine the biomechanical evidence that supports the use of such im...

—Universal elemental homology (UEH) underpins recent understanding of peristomial and ambulacral elemental homology of pentaradiate echinoderms by providing a uniform set of terminology to construct phylogenetic characters. Variation in the expression of these elements provides evidence for phylogenetic relationships. Two nonhomologous sets of plates border the peristome and are associated with...

Anchor plates may be made of steel plates, precast concrete slabs, poured concrete slabs, timber sheets and so forth. In this study, uplift resistance of strip anchor plates embedded in cohesion less soils was assessed by conducting previous works. The previous experimental works mentioned that behavior of horizontal strip anchor plates embedded in cohesion less soil has been assessed by small-...
