In this research Euler plate buckling stress
([[sigma].sub.cr]) is measured against plate slenderness.
where [A.sub.g] is the gross area of the section and [F.sub.crf] is the limiting flexural buckling stress
given by (2), depending on the level of the slenderness ratio, KL/r.
The CUFSM software provides signature curve to obtain critical local and distortional buckling stress
values which is used to calculate the strength in DSM.
The stress in the descending part of elastic buckling also increases with an increase of [r.sub.sf.sup.-], until the buckling stress
It is well known that as the plate thickness increases, the shear effect which leads to reduction of the critical buckling stress
where [PHI] is the plasticity reduction factor and depends on the ratio between the elastic hoop buckling stress
([[sigma].sub.E[theta]R]) and the yield stress of an imperfect cylindrical shell material.
No significant influence of the self-weight on the buckling stress
It revealed that the using CFRP to slender sections increases axial capacity, strength-to-weight ratio, and elastic buckling stress
up to 4 times.
Table 2 lists the buckling stress
of all the simulation models.
Under compression, the maximum buckling stress
of the nonfunctionalized CNT is the largest, followed by FCNT-1 as the second largest and F-CNT-4 as the smallest (see Figure 7).
where [f.sub.y] and [f.sub.cr] (the stress at which a material failed by crippling/buckling) are the yield stress and ultimate elastic buckling stress
To this the fact that the distance between the holes in perforated plates is also a parameter which in interaction with others affects the value of the critical buckling stress
should be added.
