I want to run a Fatigue Analysis using the S-N Method.
First i tried the S-N tutorial from the OptiStruct_14.0_Tutorials PDF starting at page 251 and it worked perfectly well.
Now i want to run the same type of Analysis with a different model and other parameters. Therefor i got some questions.
First of all i created an own .csv document with a new amplitude. the first problem is, that i need to run 2.000.000 steps but only made 333.333 Steps in my .csv data, so i need to
repeat my sequence 6 times in a single Solver run to reach this 2.000.000 times. So i need to know how to set this up.
The second problem is the material. In the tutorial the material used is aluminium, but i need to use steel in my analysis. Therefor i need to type in some values, such as: UTS, SRI1, B1, NC1 and SE. Could anybody tell me what those shortcuts mean and where i could get my values from for those shortcuts for steel.
My last question is if there is a pdf where i can check up all the shortcuts used in Hyperworks, because there are some which weren`t explained during the tutorial.
I would be very pleased if someone could help me quickly, because i need those information's for my study's.
Greetings
Christian
