How to carry out rain flow cycle counting using Altair Compose by importing a Load history file and elements composite stresses (.h3d) and then view results in HyperView/HyperGraph ?

sagar hiremath

Hello,

I am doing a project on High Cycle fatigue analysis of a Wind turbine Blade. I have performed the composite stress analysis in OptiStruct by applying PCOMPP property card to elements and have stress results in .h3d file.

Now , I want to import the h3d file along with a load history file(.csv) in Compose to perform Rainflow Cycle counting and view results in HyperGraph/HyperView .

Steps for Composite Fatigue Analysis:

1. Read composite Stress results + load history file

2. Rain flow Cycle counting

3. Allowable cycle calculation (CLDs) (Equation)

4. Damage summation (Miner's rule) - > Damage and life 

 

Could you please help me in performing these steps in Compose ?

Thanks & Regards,

Sagar
