Am modeling,GFRP t-up ribs concrete bridge deck but experiment and FEM doesn't agree. Because doesn't show any failure.
Concrete is modeling is using CDPM
GFRP rebar as isotropic only with Poison ration and elastic modulus
GFRP TUp ribs as anisotropic using engineering constant
Your graphical screenshot and question need to be well cleared to give way for contribution. let us no the real problem to tackle
@Engr.charles Kennedy,am faced with the proplem of mode of failure,ie,the FEM give only the ultimate load but doesn't show failure.
Dear Debela,
The concrete failure model has not been entered correctly and needs to be checked again. Also, if the failure criterion for CFRP is not defined, the softening part of the curve will not be formed properly.Be sure to use a failure theory such as Hashin failure theory for composite materials.
