Let's say after my analysis, I get σv = 208MPa. … Web• The safety factor is 1.25 The “+0.01” is to avoid division by zero for elements that may have no stress. With the different Femap contour tools, you can then plot the stress …
In engineering, a factor of safety (FoS), also known as (and used interchangeably with) safety factor (SF), expresses how much stronger a system is than it needs to be for an intended load. Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
