Ključne reči: ploče u obliku paralelograma; poprečno savijanje; maksimalna defleksija; odnos konformalnog radijusa; tehnika interpolacije faktora oblika
Keywords: parallelogram plates; cross bending; maximum deflection; conformal radius ratio; form factor interpolation technique
Sažetak
U radu se opisuje poprečno savijanje elastičnih prosto oslonjenih izotropnih ploča i ploča sa uklještenom ivicom pri ravnomerno raspoređenom opterećenju. Predlaže se upotreba tehnike interpolacije faktora oblika kako bi se odredila vrednost maksimalne defleksije ploče; i odnos unutrašnjeg i spoljašnjeg konformalnog radijusa kao geometrijskog argumenta jer se predlaže da se geometrijski argument upotrebi umesto faktora oblika. Ovakva zamena omogućava veću tačnost.
Abstract
In the article the task of cross bending of elastic isotropic plates with simply supported and clamped edge from the action of evenly distributed load is described. It is suggested to use form factor interpolation technique to determine the value of maximum plate deflection; and the ratio of inner conformal radius to the outer as a geometric argument is proposed to be used instead of form factor. Such replacement allows the increase of the technique accuracy.
