I am modelling a RC beam reinforced with externally bonded FRP sheets. I want to check the failure of FRP composite for which Tsai-Wu failure criteria can be used. I want to how can we implement this failure criteria in ANSYS apdl and what input or mechanical properties of the FRP does it required?
yes gentlemen. we can implement Tsai-wu failure criteria for FRP SHEETS using ANSYS APDL . As the stability of the materials depend upon the material property and geometry of the material we have to give all input parameters as required in the software and the same results may be compared with MSC.NASTRAN for validation.(boundry conditions also decides the failure criteria)
Tsai-Wu is an-isotropic yield criteria. So you have to define 21 elastic constant values via input. You can access this criteria is accessible in
the General Postprocessor.
– Main Menu > General Postproc > Failure Criteria
– You have to define the constants for each temperature and
material property, as needed
– Equivalent commands are FC, FCLIST, and FCDELE.
Thank you P. R. Jeyakrishnan and Muhammad Ajmal for the reply.
follow the steps... 1.Properties-> assign material properties for anisotropic material
2.Main Menu -> General Postproc -> Failure Criteria
3.commands are FC, FCLIST, and FCDELE.
