TensionOnlyMaterial

[tonyqwert]

Hello all!

I am a new user of this software. There is a type of material named "TensionOnlyMaterial" that I don't know how to use.

My code is:
"wipe
puts "System"
model basic -ndm 2 -ndf 3
puts "node"
node 1 0.000E+000 0.000E+000;
node 2 0.000E+000 1.000E+000;
puts "rigidDiaphragm"
puts "mass"
puts "restraint"
fix 1 1 1 1;
puts "Equal DOF"
puts "material"
uniaxialMaterial Steel01 1 1 1 0;
uniaxialMaterial TensionOnlyMaterial 2 1;"

And, here is the error pops up:
"WARNING could not create uniaxialMaterial TensionOnlyMaterial"


Thanks!!

You should use this syntax:

uniaxialMaterial ENT $matTag $E

It's undocumented, and different from ENT (Elastic-No-Tension) ...

uniaxialMaterial TensionOnly 2 1

The model you mentioned is elastic in compression direction. What I am trying to find is a elastic-plastic model in tension direction.

uniaxialMaterial TensionOnly 2 1

I've tried. It still doesn't work...

It may not be in the latest OpenSees.exe executable yet. I believe it's in the Python module though.
