ABAQUS/Explicit - Contact Noise
ABAQUS/Explicit - Contact Noise
(OP)
Hello people,
I'm a beginner in ABAQUS (learning since april) and I have a problem with contacts. I'm using surface-to-surface contact with two pieces, the one deformable being the slave and the other being the master. I'm always getting the warning "The slave surface nodes have much larger masses than the nodes on the master surface. Significant contact noise may result." I tried to modify mass-scaling , but it didn't work. I don't know if that's the cause of an oscillating kinetic energy and internal energy. I'm thinking of changing the master and slave surface, but it doesn't make sense with the tutorial of ABAQUS. I would very much like an insight...
Thanks in advance,
JuKnip

I'm using pure master-slave contact with weight parameter by default. I have changed the mass-scaling and I'm using penalty for friction formulation.
And one question, is it normal for the internal energy to oscillate?
Thanks already for the replies =) (and sorry for the english)
