Comparing both calculations the deformation is only doubled but stress increases rapidly when adding a torque.

With DesignSpace VPE engineers are able to see these consequences immediately and can modify their 3D Cad model based on DesignSpace results.

"Buckling Solution - First four modes only" contains the calculated response for "Demonstration Model" given loading conditions defined in "Buckling".

It was selected that the program would choose the solver used in this solution.

Comments:
Not only strenght- and stiffness calculations can be done. With DesignSpace VPE is able to perform the following calculations for you:
- strength and stiffness
- heat
- natural frequencies
- buckling
Due to the construction of this beam (local) buckling could be relevant.

3.3.1. Buckling Results

Buckling results apply to all active parts in "Demonstration Model".

Table 3.3.1.1. Buckling
Name	Figure	Mode	Load Multiplier	Alert Criteria	Comments
`"1st Buckling Mode"`	A3.2	1	10,321.51	none	At buckling the result is not a force or a stress but a sort of a safety factor. We applied a force of 1 N; the result of the first buckling mode is 10322. This means the buckling load is 1 * 10322 = 10322 N.
`"2nd Buckling Mode"`	None	2	92,300.74	none	None
`"3rd Buckling Mode"`	None	3	224,635.38	none	None

A5. Glossary

Alert Criteria: Alerts cause ANSYS DesignSpace to flag results that exceed minimum or maximum allowable values.
Bonded Contact: Prevents contacting regions on selected surfaces from sliding or separating. "Glues" the surfaces together.
Bounding Box: A three-dimensional cube aligned to the global x, y and z axes that exactly contains a part or assembly.
Convergence Tracking: Convergence tracking causes ANSYS DesignSpace to iteratively refine the solution until the criteria for allowable change in the result is met or the maximum number of loops is exhausted.
Frictionless Contact: Models standard nonlinear unilateral contact. Allows free sliding and gaps to form at contact interface.
No Separation: Prevents contacting regions on selected surfaces from separating. Frictionless sliding may occur.
Relevance: Defines the acceptable accuracy for a part and valuates the importance of parts in an assembly. The relevance range extends from -100 to +100, where -100 implies maximum software speed and +100 implies maximum accuracy in calculating results.
Rough Contact: Nonlinear contact that allows gaps to form at contact interface but does not allow sliding (infinite coefficient of friction).
Scope: Filters a result to selected geometry. If combined with convergence tracking, focuses refinement activity on the selected geometry.
Simplification: A software technique for removing negligible geometry for parts to improve reliability, increase speed and reduce overhead. The simplification range extends from -100 to +100, where -100 implies aggressive simplification and +100 implies highly selective simplification.
Visible: A user preference that controls the visibility of parts in figures in this report. Unlike suppressed parts, invisible parts are fully considered in the calculation of results.
