How do you reduce factor of safety in Solidworks?

Contents

What is a good factor of safety solidworks?

Many codes require a minimum factor of safety between 1.5 and 3.0.

How is factor of safety calculated in Solidworks?

SW calculates the FOS as you calculate it manually by dividing the calculated stress from the FEM results by the yield strength which is a material property. To view it on SW you can right click on the results in the feature manager design tree and the choose the “define factor of safety plot…” the follow the wizard.

What is margin of safety engineering?

Noun; margin of safety – the margin required in order to ensure safety; in engineering the margin of safety is the factor of safety (strength of the material divided by the anticipated stress) minus one.

What is safety factor in Simulation?

Safety Factor is an important result that you can use to evaluate how suitable a design is for its intended application. The safety factor indicates if a design is likely to survive unharmed, bend, or break when subjected to the applied loads.

What is a good factor of safety?

General recommendations

Applications	Factor of Safety – FOS –
For use with highly reliable materials where loading and environmental conditions are not severe and where weight is an important consideration	1.3 – 1.5
For use with reliable materials where loading and environmental conditions are not severe	1.5 – 2

Is a higher or lower factor of safety better?

In general, a high factor of safety means a heavier component, more upscale material and an improved design. A factor of one means that the stress is at the allowable limit. Less than one means likely failure.

Can factor of safety be less than 1?

The factor of safety is the ratio of the allowable stress to the actual stress: A factor of safety of 1 represents that the stress is at the allowable limit. A factor of safety of less than 1 represents likely failure. A factor of safety of greater than 1 represents how much the stress is within the allowable limit.

What does a safety factor of 3 mean?

If there is a part with a required design factor of 3 and a margin of 1, the part would have a safety factor of 6 (capable of supporting two loads equal to its design factor of 3, supporting six times the design load before failure). A margin of 0 would mean the part would pass with a safety factor of 3.

How are factors of safety determined and on what basis?

Determining the factor of safety:

Ductile materials use yield strength to determine the safety factor. Brittle materials use the ultimate strength. Yield strength: Determines the safety factor until the start of deformation. Ultimate strength: Determines the safety factor until failure.
