Need Finite Element Anylsis(FEA) on special design nut fastener

I have a special design nut fastener a "permanent nut" (patent pending) and need Finite Element Anylsis(FEA) done on it. Attached is my fastener design in autoCAD 3D, 2D and pdf in size 1X8 American SAE and 1/2X13 pdf.

My permanent nut is an all-metal, one-piece self locking nut that functions like "two nuts torqued down and welded together(TNTDWT)". It spins-on and installs like a conventional nut and has the same vibration resistance as TNTDWT.

My permanent nut can be thought of as a conventional nut attached to a threaded conical washer, when the torque pressure builds the conical washer starts to flatten. When installed equal pressure/pre-compression exists on both sides of the washer. The difference is that the internal nut pressure/pre-compression is permanent like TNTDWT.

I want to determine the minimum and maximum torque in foot/pounds for nut sizes 1X8 and 1/2"X13 in SAE American using the following standards:

ASTM A563-Grade 0, ASTM A563-Grade A, ASTM A563-Grade B, ASTM A563-Grade C, ASTM A563-Grade C3, ASTM A563-Grade D, ASTM A563-Grade DH, ASTM A563-Grade DH3

ASTM A194-Grade 1, ASTM A194-Grade 2, ASTM A194-Grade 2H, ASTM A194-Grade 2HM, ASTM A194-Grade 4, ASTM A194-Grade 7, ASTM A194-Grade 7M, ASTM A194-Grade 8, ASTM A194-Grade 8M

SAE J995-Grade 2, SAE J995-Grade 5, SAE J995-Grade 8

-----

All of the above standards have a specific material formula (steel, steel alloy).

For example: 1X8 SAE Grade 2, torque minimum (to fully flatten cone washer) 80 ft/lbs., maximum torque 400 ft/lbs.

In other words I will need the min. and max. torque for my permanent nut using the materials in the above standards in nut sizes 1X8 and 1/2X13.

Please give me your cost and how long it will take you. I will be happy to answer any questions you may have.

Thanks you.
