Topic: Plastic strain
Since I am using material parameters based on my experimental investigation, I have question regarding value of plastic strain at compressive strength. According to the theory manual and explanation of the parameter in Atena Science GiD interface, it can be calculated based on following formula FC/E. However when I am checking the formula according to the default Concrete EC2 materials I am not getting the same value. Consequently I used default value for matching concrete class with my examined materials. But I have Young's modulus value in case of one material subsequently lower so I would like to check how the value can be calculated.
