Will Cosmos Express tell me that a bolt will fail when I want it to?

Good Afternoon Group,

I have a bolt made from 1045 that has a 1/4" radius groove around the outside diameter. The purpose of the groove is to reduce the bolts' tensile strength so that it will fail at a given amount of tension.

If I give Cosmos Express a Factor of Safety of 1, input the tension value and have it optimize the design, provided I have the parts' material properties correct will it give me the results I want?

Regards,
Randy
