In Abaqus, when using imperfection from buckle analysis, how do we determine the scale factor?
*IMPERFECTION, FILE = (my odb file from buckle), STEP=1
Mode number, scale factor
What does the scale factor represent? For example, I want my out of plane displacement(U3) to have an imperfection of...
I am using steel with bilinear elastoplastic material. When I apply a compressive load on a beam (wire) element, After yield, I am getting a negative force-displacement curve for U3. What does that mean?
In Abaqus, when the documentation says "can generate linear as well as nonlinear constraints" for MPC subroutine, does that mean, it is for Non-Linear material regime?
In the Abaqus, I have a beam and column made of shell elements (S4R). They are connected with Tie constraint. When I run the analysis, there are node sets under "WarnNodeBCInactiveDOF" and those are the ones at the connection between beam and column. What might be the reason for this? This is...
What could be the best way to connect the 3D wire beam with the solid surface?
Initially, I tried using MPC Beam or Kinematic Coupling from the Interaction module but I am not getting expected results from these constraints.
There is some space between the two plates.
In ABAQUS, if we define 5 equation constraints such that we restrain 2,3,4,5,6 degrees of freedom, shouldn't the U2, U3, UR1, UR2, and UR3 for the nodes be equal given that Poisson's ratio is 0?
In the below figure, the local axis is defined such that the X is parallel to the longitudinal axis of the left beam. In ABAQUS, if I define kinematic coupling say constrain U1 with the master for left beam and slave for right beam, will U1 still be the axial/longitudinal axes for the left beam...
In the ABAQUS, my member is a beam 127.5625 in. long with a uniform rectangular cross-section of 3.5 in2. I input a bilinear steel property with true stress of 42.06 ksi, plastic strain 0, and ultimate true stress of 72 ksi and plastic strain 0.18. This came from a yield point of 42 ksi and...
In my ABAQUS, I have two beams and have applied axial compression to one of the beams. Both the beams have the same non-linear material property but different geometric properties. The other beam interacts with the first beam (the one in which the load was applied) by the following interaction...
In ABAQUS, if we apply kinematic coupling between two nodes, say node 1 is master and node 2 is a slave, and constrain U2 and U3, shouldn't U2 for node 1 = U2 for node 2 and U3 for node 1 = U3 for node 2 be true?
I have two wire beams parallel to each other, they are at an angle with horizontal. I tried coupling the U2, U3, UR1, UR2, and UR3 using a local coordinate system with nodes on one beam as controlling and nodes on the other as slave. They are aligned in elastic range but seem to not move...
I tried connecting the end of a wire beam to a solid using an MPC beam constraint. The analysis runs fine in linear range but doesn't give expected results in a non-linear material regime. Can someone help me understand how I should connect those two?
Hello,
I have been trying to connect beam(wire) to the surface of a solid element. I used a kinematic coupling with the tip of the beam as master and the surface of solid as a slave, and it seems to be working fine in the linear range. But if I input non-linear material properties to the beam...
