SS-V: 1150 Buckling

Test No. VS16 Find the critical compression load at which the cantilever beam buckles.

Definition

Dimensions: L = 1000 mm, b = 20 mm, h = 20 mm

Where,

b: Breadth of the rectangular section.
h: Height of the rectangular section.

The material properties are:

Properties: Value
Modulus of Elasticity: 2.1e11 pa
Poisson's Ratio: 0.3

Results

The following table summarizes the critical load.


	Reference KN*	SimSolid KN
Critical Load	6.90	6.908

*The reference result is calculated by:

P_{c r} = \frac{π^{2} E I}{{(K L)}^{2}}

Where,

$E$: Elastic modulus.
$I$: Area moment of inertia.
$L$: Length of the beam.
$K$: Effective length factor = 2 for cantilever beam.
