• Attempted to get material samples by using sharpened square. Failed because samples are much to distorted. Will have to mold samples instead.
• Eliminated damping in steel components of model. Literature suggests damping in steel is minimal (<0.01)
• Determined most model parameters. Need to get elastomer properties still. can only be obtained experimentally though,so holding that up.

• Working Model created
  • lumped spring mass config (on Yoda/Sphan/IFOS/catheter_model.w2d)
  • flexbeam model (Yoda/Sphan/IFOS/catheter_model_beam.w2d )
  • Need characteristics from YL to make model mor eaccurate
• Dr. Ellen Kuhl
  • doing finite modelling of heart and getting material characteristics
  • initial stages currently.

• 3 DOF lumped model created (pg 152 in notes).

To Do:

• Model in Working model (pg 154 in notes)
• Try to model in CoSMOS?
  • install Solidworks
• Do material testing
  • pick up square tube for sample extraction
  • coordinate with James re: time
  • followup with Kuhl
