How can be determined the value of "Maxps Damage" and consequently "fracture energy parameter of Damage Evolution" for concrete in ABAQUS?
Dear Mehmet Safa Aydogan
Maxps Damage usually used for crack growth by XFEM method. You can carry out three point bending test on your concrete sample and use fracture stress as Maxps Damage. From maximum stress until fracture became complete in stress-strain curve, you should calculated area of this region of diagram as fracture energy and enter to "fracture energy parameter of Damage Evolution",
Dear Mehmet,
The following paper is a good reference for estimating fracture energy and the evolution of damage parameters in concrete.
B. Alfarah, F. López-Almansa, S. Oller, New methodology for calculating damage variables evolution in Plastic Damage Model for RC structures, Engineering Structures. 132 (2017) 70–86.
The mesh density must be carefully calibrated. The paper offers a very useful methodology.
Best regards.
