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 | 6.904 |
*The reference result is calculated by:
Where,
Pcr = π2EI(KL)2
- E
- Elastic modulus.
- I
- Area moment of inertia.
- L
- Length of the beam.
- K
- Effective length factor = 2 for cantilever beam.
