Abstract. The purpose of this article
is to reconsider an example of the spherical shell, which has been used
for more than ten years in monlinear finite element analysis tests. However,
the numerical results were compared, as a rule, with the analytical results
concerning the shell (a rotational paraboloid) having only one spherical
point.
Keywords: Finite element model
validity, spherical shell, shell with spherical point
JEDNO ISKUSTVO
U PROVERI VALJANOSTI MODELA
PRI ANALIZI SFERNE
LJUSKE METODOM KONAČNIH ELEMENATA
U radu je analiziran primer sferne ljudske,
koji se više od deset godina koristi u testovima iz nelinearne analize
konačnim elementima. Međutim, rezultati proračuna se, po pravilu, porede
sa analitičkim rezultatima koji se zapravo odnose na ljusku (rotacioni
paraboloid) sa samo jednom sfernom tačkom.
Ključne reči: Valjanost KE modela,
sferna ljuska, ljuska sa sfernom tačkom.
