Abstract: 
It is now common to characterize the tensile behaviour of fibre reinforced concrete by bending tests rather than by direct tensile tests. Then it is fairly common today to apply reverse analysis to extract the tensile constitutive equation of the material. For the case of thin plates showing a bending hardening behaviour, a new explicit method (which does not need any numerical solver) allowing performing reverse analysis into equivalent strain is proposed which starts with an experimental moment-deflection relationship to get tensile stress-strain constitutive relationship. The great advantage of this explicit approach is its easy programming and it allows to quickly manually adjusting a constitutive material relationship on the experimental results without any data pre-treatment. Two specific application cases are presented showing how this methodology could accelerate the use of UHPFRC in real applications making easy the analysis of characterization tests.
