HEEDS DOE: Crush of Composite Tubes
A Design of Experiments (DOE) study was performed using HEEDS Professional to investigate the main energy-absorbing mechanisms during quasi-static crush of a circular composite tube.
Failure mechanisms such as material failure, delamination, friction between plies and friction between a metallic initiator and the tube were explicitly studied.
The results confirmed that friction between the tube and the initiator was the dominant mechanism, representing approximately 50% of the total energy absorption.

Imposing Constraints on Design Variables
HEEDS Professional Tip #1
solving engineering design optimization problems, it is common to have design
variables that are semi-independent. That is, the variables vary independently
within a range, but the range over which they vary is dependent on the values
taken by other variables. For example, three variables may be independent, but
the sum of these three variables must be equal to a prescribed value.
This technical tip demonstrates a method for redefining your HEEDS optimization problem to efficiently accommodate semi-independent design variables.
