Modelling non linear springs in abaqus

  1. Sep 5, 2011 #1

    First i modelled 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?

    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
