does anybody know how to use the material model no:185 in ls dyna for modelling cohesive zone elements for analyzing the crack propagation in a ct specimen made of steel?

Madam,

I want to make a simple composite structures of concrete embedded steel in abaqus. (If I am wrong kindly say) I have creted a "dependent" instances in the assemble module after doing the mesh. Then I have made the interaction with the step-1 and made a "surface to surface contect (standard)" having the master (concrete) and slave (steel) with contact (friction) property.

1. i am doing M.E in tamil nadu....am doing final year project in composites material...i.e., delamination analysis of composite material in glass fiber with epoxy.....i do the analysis in ANSYS 12...i saw in ANSYS there is APDL program as same as my project...i.e., VM 248.......i need step by step instruction of APDL program.....pls hepl me as soon as possible..........

Hello,

I am trying to model a reinforced concrete beam in ANSYS 11. This software is new to me and I am having some problem in defining the reinforcement using the software. I have found some of the similar work in ANSYS have used SOLID 65 for concrete and LINK 8 for reinforcement. But I don't know how to input the link element as reinforcement. Since I am just starting to use ANSYS, can somebody please help me by providing some of the basic steps to model a reinforced concrete beam?  

Thanks. 

Hi everyone,

I am trying to model composite failure in abaqus. I used USDFLD to check different failure mode (fiber tension/compression, matrix tension/compression,..) based on available theory of failure. After checking the failure, if any element fails, the material property like stiffness will suddenly reduces to near zero. At this time i need to chnage material stiffness in UMAT and getting new stress distribution.

My problem is in the input file (inp file) how can I use both command for USDFLD and UMAT?

 Here is a part of my input file:

Hello all,

   I am faced with a problem of modelling a reinforced concrete beam
wrapped with FRP using ANSYS. Can any one help me out please?

I would appreciate your response about this issue. Thnk ya all
