I am trying to model an energy dissipater element that can undergo plastic deformation when contacted by a body, e.g. elastic perfectly plastic relationship
I have tried using a sensor as described in Article Number
000002688:
What I have so far:
-----------------------
Sensor event definition
.MODEL_1.Deformation - SENVAL(DeformationSensor)
Sensor event evaluation:
.MODEL_1.Deformation
SForce:
IF( .MODEL_1.Deformation: forceValue, 0, 0 )
Questions:
-------------
I am finding it difficult to figure out how to incorporate the plastic deformation. According to me plasticDeformation = SENVAL(DeformationSensor) therefore the force becomes (where force value: f= min(kx, plasticForceValue):
IF( .MODEL_1.Deformation + plasticDeformation: forceValue, 0, 0 ) but this is obviously incomplete and incorrect.
Is the sensor approach correct for this application, or do I need to look at doing a subroutine? Is there another approach that will work?
Sorry, I've been on vacation and have not seen your question until today. have you already solved your problem?
This can clearly be done using a sensor. I need a little time to work out the equations, but I have done this in the past for emulating elasto-plastic soil properties.
