COLOUMB FRICTION LAW

COLOUMB FRICTION LAW

COLOUMB FRICTION LAW

(OP)
hello,

iam modelling a concrete filled steel tube and try to adjust the friction in abaqus. does anyone know if the *friction option especially the coloumb friction law in abaqus calculates the pressure (for tau=pressure*mue) or is the only way for using coloumb friction to enter a constant pressure in the *friction option. i want to model especially the pressure due to poisson effect under axially loads on the steel tube and therefore the resulting friction......

my results dont show any friction due to poisson....

thanks,
barney
