I make a master research about concrete beam strengthened using FRP strips and u-wraps. i do the FEA for my test samples in ANSYS so,i hope if someone can tell me what the better element is for simulation of strips and which one for u-wraps. another question, is the local axes effective in ansys and how i can control it.
Many thanks

i make FEA for my master research in ANSYS PRO., i simulate a prestressed concrete beam with two precast units connected by contact element (CONTA.52). i used solid 65 for concrete modelling and link 8 for for prestressing steel with initial strain, i entered the stress strain curve for the concrete with linear isotropic, concrete and multilinear isotropic in five points as below:
strain=0.0004 stress = 12 Mpa
Strain = 0.001 stress = 30 Mpa
Strain = 0.0015 stress=37.5 Mpa
