Many formulas of estimating buckling stress
and moment of the cylinder under bending have been explained, but not considering the internal pressure.
It revealed that the using CFRP to slender sections increases axial capacity, strength-to-weight ratio, and elastic buckling stress
up to 4 times.
In the compression bending test, buckling behavior might influence stress-strain behavior after buckling, so buckling stress ([[sigma].
In addition to evaluating buckling stress by Southwell's method as just described, we also predicted it using Euler's elastic buckling equation and Engesser's tangent modulus equation (Timoshenko and Gere 1963).
Figure 6 shows plots of the buckling stress [[sigma].
Prediction of the buckling stress of intermediate wooden columns using the secant modulus.
Another aspect of this work is the investigation how the layers arrangement order in the laminate affects on the cell's critical buckling stress.
The critical buckling stress values for hinged supported bearing structures with 10% of 90[degrees]-layers for structures with different order of the layup are obtained and shown in table 2.
1975) assumed that the failure will occur when a certain region of the web yields as a result of the combined effect of the inclined tensile membrane stress field and the web buckling stress
crg]--FM) buckling stress of all columns obtained from LSA and along with [[sigma].
n DSM] estimates depend on the value of the critical buckling stress, this table discloses different estimates for each critical stress value.
Substituting these two expression in the Euler buckling stress
