Abstract EN
This paperfocuses on the studied the structural instability caused by perforated andunperforated stiffened plate having all round simply supported boundary conditions subjected to in-plane uniaxial compressive load and also to the unperforated and perforated plateare reinforced with two stiffeners in (longitudinal, transverse and combined)directions.
The aspect ratio, area ratios, and number and direction of stiffeners are the parameters considered.The analytical solutions are carry out by energy method.
A finite element analysis is carry out by software Ansys.
Results show that the presence of a three central circular perforations reasondecreases in buckling load factor of plate and the stiffeners can be used to reduce this decreasing.
It is also concluded effect of transverse stiffeners which is less than that of longitudinal stiffeners for both unperforated and perforated plate.Increase the cutout ratio to η=0.15 at δ=0.125, β=1 will lead to decrease the K (10, 21 and 10.6)% for SSSS2L3, SSSS2T3 and SSSS4C3 respectively at when compare with SSSS2L0, SSSS2T0 and SSSS4C0.The economical design of structuresislikely by presenting stiffeners of optimum size.
