Kalsi
Engineering, Inc. has been actively involved in developing the
elastomeric products using finite element analysis (FEA). FEA of
elastomers is significantly challenging and requires an insight into
the material deformation from the mechanics point of view.
Hyperelastic material models are used for the FEA of the elastomeric
products. There are a variety of hyperelastic material models to
choose from. Answers to the following questions should be sought by
the analyst before performing hyperelastic FEA.
-
Which
hyperelastic material model should be used?
-
How to obtain
the constants necessary to develop the material model?
-
Is it necessary
to obtain elastomer stress-strain data even to perform
preliminary elastomer FEA?
-
What kinds of
tests need to be performed to obtain the stress-strain data to
device the hyperelastic material model?
-
What if the
developed material model is unstable? Can the instability be
eliminated?
-
What if the
expected maximum strain in the elastomeric component is beyond
the range of the test stress-strain data from which the material
model is developed? Or in short, how to utilize the limited test
data?
-
What are the
limitations of the hyperelastic material models?
Our years
of experience and strong knowledge base enable us to provide a
comprehensive consulting service in the area of elastomer FEA. |
