Convergence issue RC beam ANSYS

Convergence issue RC beam ANSYS

Convergence issue RC beam ANSYS

(OP)
Hi,

I need help please. I am trying to analyze simply supported reinforced concrete beam using ANSYS APDL 14.5 I am using solid65 for the model and reinforcing the beam using solid65 with smeared rebars for both shear and moment. The load is uniformly distributed force on all nodes. I entered the material models for both steel and concrete as recomended by other works. The problem is that the solution losts convergence at the first moment that concrete reaches its tensile crack stress (Uniaxial Cracking Stress). I tried to change the Open Shear Transfer Coe. and the Uniaxial Cracking Stress but what I get every time is that solution losts convergence when concrete stress reches its Uniaxial Cracking Stress of the material model. Any sugesstion please.

RE: Convergence issue RC beam ANSYS

estimado compañero podrías subir la carpeta de archivos comprimida de tu proyecto. (ya que si subes solo el archivo wbpj no podre ejecutarlo para verlo). Soy algo nuevo usando el ansys pero empiezo a familiarizarme con este software, aunque como lo que pides es una sugerencia podría ser que no esta correctamente definido en material, o el tipo de análisis, o el mallado tiene nodos desconectados bueno hay muchas posibilidades pero sin ver el modelo creo que no podre ayudarte mucho.
