ICAST 2026 - The 36th International Conference on Adaptive Structures and Technologies

 Payments Accepted and Processing Fee
Registration must be paid using a credit card or a U.S. bank-issued check. A 3% processing fee will be added to all credit card payments at the time of check out.
UT employees and students: See below regarding payment instructions.

University of Tennessee Employees and Students
All UT employees and students should use a department account to register (and not a personal credit card or department PCard). For payment, register online with your selections added to the cart and check out with a balance due. Subsequently, email a department account number along with your name, NETID, and balance amount to: Conferences@utk.edu. For any credit card refunds processed due to not paying with a departmental account number there will be a 6% credit card processing fee based on the sale amount.  The 6% fee will be withheld from the refund to the card used.

Cancellations
To qualify for a refund on conference registration fees, send a written request by 15 May, to UT Conferences, ATTN: GARD, P.O. Box 2648, Knoxville, TN 37901-2648, or to Conferences@utk.edu. An administrative fee of $50 will be assessed. No-shows and late cancellations will not be refunded; however, substitutions are encouraged.

Splitting Payment Option:  Some organizations will only approve reimbursement of conference registration (and not field trips, workshops or merchandise). If this is the policy with your organization, you can pay for registration using one method and pay for field trips, workshops and merchandise using another method.  To do this, pay the registration amount that is due today (default option) and a link will be emailed to you for paying the remaining balance by 15 May 2026.  If you are approved to pay for all items using one method, check the “Pay Balance” box below and the entire amount (registration + field trips) will be required at checkout.  NOTE: If conference registration is the only item in your cart during checkout, you will not see the split payment option.
