A punch going into a material with fixed bottom
A punch going into a material with fixed bottom
(OP)
I'm very new to abaqus and am currently working on a problem of a cylindrical punch compressing into an elastic/plastic material underneath it
I've made a cae which seems to start building but I constantly get the same problem of
ELEMENT TYPE C3D6 USES THE REDUCED INTEGRATION IN Abaqus/Explicit AND WILL BE REFERRED TO AS C3D6R FROM HERE ON
ELEMENT TYPE C3D6 USES THE REDUCED INTEGRATION IN Abaqus/Explicit AND WILL BE REFERRED TO AS C3D6R FROM HERE ON
There are 2 warning messages in the data (.dat) file. Please check the data file for possible errors in the input file.
The slave surface nodes in node set WarnNodeMassRatio3fix-Step1 have much larger masses than the nodes on the master surface. Significant contact noise may result. Suggested workarounds include setting the WEIGHT parameter so that what was the master surface becomes a pure slave surface in the contact pair, using mass-scaling to adjust the ratio of nodal masses, or using the penalty contact algorithm. See the status file for further details.
I was wondering whether anyone had any advise on the matter or a similar cad program which I can work from?
Thank you very much for you time

RE: A punch going into a material with fixed bottom
I have these two errors
1. Boundary conditions are defined at the nodes contained in node set WarnNodeBcIntersectKinCon. In addition the nodes are also part of a surface involved in kinematic contact. The kinematic contact constraint will be overridden by the boundary conditions in case of a conflict. Penalty contact may be used instead.
2. The slave surface nodes in node set WarnNodeMassRatio3fix-Step1 have much larger masses than the nodes on the master surface. Significant contact noise may result. Suggested workarounds include setting the WEIGHT parameter so that what was the master surface becomes a pure slave surface in the contact pair, using mass-scaling to adjust the ratio of nodal masses, or using the penalty contact algorithm. See the status file for further details.
I have a boundary condition at the bottom of the material, holding it in place, and the other is one holding the centre axis of the punch in place
I can't for the life of me figure out what the second error is telling me however.
Thank you for your time
