Stress-strain curve for thin-walled steel structures at elevated temperatures

ploting nominal stress-strain and true stress-strain curve for use in Abaqus.

This program calculates mechanical properties and plots stress-strain curves for thin-walled steel structures at elevated temperatures.
It will write data into excel files which could be used for input to FE programs such as Abaqus Unified FEA.

the input data for Abaqus is true stress and plastic strain.
the plots are nominal stress and nominal strain.

• Inputs: Elastic modulus, based yield stress.

• Outputs: nominal stress - strain curves at elevated temperature, true stress - plastic strain for using in Abaqus
