Force required Displacement in 2D-Simulation

Michael Kuhn Jan 31, 2018 8:44 AM

Hello fellow Solidworkers,

Im trying to simulate the Deformation of two polymer hooks (picture attached) - Non Linear, Given Displacement, 2 Dimensional analysis.
I displace the upper hook in negative Z (1,5mm).
Now i would like to see how much force is needed to reach the given displacement.
But now the question in my brain arises if it is even possible to evaluate the force needed in a 2D-Deformation Model.
Is there any possibility to define the thickness of the geometry ?

Many thanks in advance,

Michael

Hi Michael,
In the definition of a 2D simplification analysis you would need to enter the theoretical section depth of the 2D cross section in order to start the analysis. The section depth you put in would determine how the program calculates the resultant force from sending your snap hook through this displacement.
Beyond that, you would just run the study then right click on 'Results' to go to 'List Result Force' and measure, what should be, the real applied force to cause that displacement.

  Good day Michael
  Do you have information about constant for your polymer's model of material?
  Would you mind provide me your geomtry please?

  Aha,
  very helpful! I thought this entry is just for displaying reasons - thank u.
  Unfortunately i´m can not share the CAD-File.
  I´am using a Non Linear Material Model. A very good website to get material data is https://www.campusplastics.com/
  There u get strain/tension diagrams which u can use to fully define your material.
  
  But take care when defining a new material via strain/tension data. Solidworks does not need strain in [%] - so don't forget dividing by 100.
