Question

I have a question during my Tensile Test of Sturctural Steel.

Ive collected all the data, can you calculate the Elastic Modulus and referring to the stress strain curve of your samples , discuss and compare the results, specify the similarities and differences if there is any and provide possible reasons.

Thanks
