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
