Cracking of the concrete cover due to reinforcement corrosion

Dear all,

 Our paper titled "Cracking of the concrete cover due to reinforcement corrosion: A two-dimensional lattice model study"
 has just been published in Construction and Building Materials. It deals with numerical modelling of cracking of the concrete cover as a consequence of reinforcement corrosion, based on the Delft lattice model framework.

characteristic Length

Hi

 

is there a way to get the characteristic length of one element? I wanna calculate xult (when the element is cracked, fracutred..). 

 I use the concrete damage plasticity model and after reaching the tensile strength i assume a linear softening with fracture energy.

 

Input are:

   Young´s modulus

   max. tensile strength

   fracture energy

 

Outpu:

   when do i reach xult or what is the plastic strain equivalent

Smeared Cracking Model in ABAQUS

Choose a channel featured in the header of iMechanica: 

I am trying to analyse a beam subject to elevated temperature using smeared cracking model for concrete. Its sequentially coupled thermal stress analysis. I am a newbie as far as ABAQUS is concerned. Can someone please help me out with the smeared cracking model. I am not able to figure the tension stiffening properties that I need to enter. Please help.
