It depends on your analyses and FRP type.there are so many FRP types with different propertis,For example the CFRP should been modelled as an isotropic linear elastic material. the unidirectional CFRP composite actually shows an orthotropic behaviour, but it was shown in many reffrences that only the axial modulus is of importance in an application of this type. The elastic modulus and strength should taken to be E(CFRP)=165 GPa and f(CFRP)=2 GPa respectively.The Poisson ratio of the CFRP composite was assumed to be 0.3
if you has more questions I'll be glad to help you.
i am trying to use solid185 for frp and inter205 for the cohesive .....these elements do not have real constant.....so how can i enter thiere thickness and failure criteria ?
i tryed this code but i am not sure that the program read it

hi brother iam trying to model rc slab with opening and strengthening that opening with CFRP sheets so i tried to select the engineering constants form the elastic window and selected the hashin damage and give it damage evloution but the CFRP still dont take more than 5 KN load till failure !!! it must take about 25 KN before failure occur please help me what should i do and to make the cfrp sheet more stronger ??by the way the parameters i used for engineering constants is

Dear Alireza,
I read this codes but ansys didn't.are you sure this codes are correct?
but i guess what is your problem.
It can be related to frp material,or concrete material.give correct amounts and run again.
other thing is mesh,if your mesh sizes is large,try smaller.
be contact with us.
best regards.

hi,
i am modeling concrete beam with frp
but what ( real constant and material models) should i use for frp....
thanks

FRP Hashin Damage
I forgot to remind that if you want to model damage parameters for FRP, you should use Hashin Damage in ABAQUS..
good luck

80000 231000 80000 0.05 0.05 0.45 3700 79655 79655
and for the jashin damage is
4100 50 4100 50 100 100
and for damage evolution is
1 1000 1 1000
my cfrp E is 231000 Mpa and tensile strength is 4100 Mpa
so the upper parameters i calaculate them from excel sheet belong to my friend
and my cfrp sheet is unidirectional
please help . . . .
