Modelling non linear springs in abaqus

Click For Summary
The discussion centers on modeling non-linear springs in Abaqus, where the user successfully created linear springs but encountered issues with non-linear springs not carrying any load. They utilized the connector builder to define a non-linear spring with a specified force-displacement behavior but did not achieve the expected results. Other users in the thread reported similar problems, indicating a shared challenge in getting non-linear springs to function correctly in their models. The conversation seeks solutions or insights from those who may have resolved this issue. The thread highlights the complexities of implementing non-linear spring models in Abaqus.

Dear,

First i modeled linear springs with abaqus: Model >> Assembly >> Engineering Features >> Springs/Dashpots >> Connect two points, In this way i can define just only the spring stiffness.

So therefore i would like to define a non linear springs. I used the connecter builder >> connected the same two points, Created connecten section: basic, axial >> Elasticity, Non linear, Force F1, Uncoupled en i defined three points of the force-displacement behaviour.

In the connector Buileder meno i Created CSYS on axis between points, axis 1 / CSYS 2: Use CSYS 1.

So fare so good i thought,

but: in my results i see that the non-linear spring doesn't carry any load, while first of all in the model with the linear spring (by using the spings/dashpot menu) the springs do carry load.

Is there anyone who have had this problem before?

Hello,
Even I get the same problem. The non-linear spring doesn't carry any force. How did u resolve this. please help me with this
 
Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
