i am working on modeling hertzian contact (general and standard conact in abaqus). i want to know how to model contact between surfaces of my assembly.  i modeled it but it gives me error saying that my regions in the model are not connected.

How should I go about? is contact modeling different than just constraining the surfaces ? 

Hello

I'v been searching for micro-plate's deflection formulas.

Please help me in finding relations

Thanks 

Hi 

I want to model the lightweight slab and since i do not have the material behaviour of the slab, i have to do testing. i was searching in internet and i got two different concept: "bending stress-strain curve" and "compression stress-strain curve". i do not know which one should i follow? and is there any difference?

Regards.

HI, everyone,

 This is pflines, i am working on the mode I\II fracture toughness.

i want to use the asymmetric four-point-bend sepcimens to get the value of KI and KII,

 but did not found a clear formulation to caculate the KI and KII,

 anyone could help me?

Hello everybody

I am simulating hydraulic fracturing operation with Abaqus. I have used cohesive elements and also utilized viscous regularization to cope with convergence difficulty. However, the problem still persists. Should I stick to regularization technique or should I write a user subroutine that will allow more flexibility. 

  Thank you

please any one tell me how i will get the shape function for the three noded beam element

i mean tell me /what is the procedure for the hermite shape function.

how the slopes hermite graphs come ,with releted to the nodal displacement (ζ)which is (-1≤ζ≥1)

Hi ppl,

I wud like to know is there any guide to model 2D or 3D woven fabric in abaqus...

plz let me no if u do...

thanks
