Abstract.
In this paper an influence of ring stiffness distribution along the shell defined through on the shell stiffness on the case on axially symmetric problem for cylindrical shell is investigated. Optimality conditions are formulated.
Key words:
shell, homogenization, asymptotic method, optimization
OPTIMALNO PROJEKTOVANA PRSTENASTA UKRUĆENJA LJUSKI
U radu su predstavljeni rezultati izučavanja uticaja rasporeda prstenastih ojačanja duž ljuske definisani preko krutosti ljuske u slučaju aksijalno simetrične cilindrične ljuske. Formulisani su uslovi optimalnosti.
