Week - 9 Material Modeling from Raw Data
Week - 9 Material Modeling from Raw Data
Aim:
To generate stress, and strain data for a given graphite iron casting image and simulate the data in a tensile model.
Procedure:
1. upload the image in Get Data Graph Digitizer. And convert graphs to excel data.
- That data is true stress and true strain.
3. convert that data to plastic stress and strain.
4.Effective stress = True stress
5.True strain= Effective elasticity strain +Effective plastic strain
Effective plastic strain = True strain - True stress / E
6. convert all in the same unit.
Select the section, ELFORM, and Thickness.
Make stress Vs strain curve.
Select the material M24 card and select LCSS.
Displacement Curve.
Select Part.
Select BOUNDARY_PRESCRIBED_MOTION_SET
