Concrete stress-strain Softening behavior?
Posted in the ANSYS Forum
#1 Sep 26, 2010
I have tried to input the following stress-strain relationship for SOLID 65 Concrete material, but I keep on getting error messages saying I cannot input negative slopes in the data table. I need to specify the softening behavior of concrete after the ultimate strength, is there any other way to specify it? Thank you in advance for your help.

hi..you can change the input stress-strain value slightly to get the positive slope...it will not create any prob in the result...try it...

but then it is not equal to strain softening portion rite? is it possible to specify the strain softening curve in ANSYS? correct me if i'm wrong. thanx in advance
