Scott Herdic's published research centers on smart materials and piezoelectric actuation — from proof-of-concept piezo-hydraulic actuators for helicopter rotor blade flaps to phase field modeling of ferroelectric domain structures. Work appeared in SPIE Proceedings (Smart Structures and Materials) and as graduate thesis work at the Georgia Institute of Technology.

SPIE Proc. 5762 · 2005

Development of miniaturized piezo-hydraulic pumps

Eric G. Chapman, Scott L. Herdic, Chaz A. Keller, Christopher S. Lynch — Smart Structures and Materials 2005: Industrial and Commercial Applications of Smart Structures Technologies

Three small, low-cost piezo-hydraulic pumps were developed, delivering up to 600 psi of blocked pressure and 338 cc/min of free flow — the smallest weighing under 90 grams. Using cofired multilayer piezoelectric actuators for low drive voltages, the pumps are suited to distributed actuation systems where pump, control valve, and hydraulic actuator are co-located, minimizing system weight and hydraulic tubing length.

Phase field modeling of domain structures in ferroelectric materials

William S. Oates, Aurelian Malbec, Scott L. Herdic, Christopher S. Lynch — Smart Structures and Materials 2004: Active Materials: Behavior and Mechanics

A phase field model based on the work of Hu and Chen was computationally implemented. The approach minimizes global free energy to simulate the evolution of domain structures through the time-dependent Ginzburg-Landau equation, focusing on the assumptions made when setting up the free energy function and their effect on model behavior.

Development of piezo-hydraulic actuation systems technology for use on a helicopter trailing edge flap

Scott Lucas Herdic — Georgia Institute of Technology

Thesis describing the development of a proof-of-concept piezoelectric actuator system designed to meet the performance requirements for actuation of a trailing edge flap on a helicopter main rotor blade. Because piezoelectric actuators produce extremely small displacements, the work amplifies their output in two stages to reach the stroke required for the flap.

About the researcher — Scott Herdic

Scott Herdic holds two degrees in Mechanical Engineering from the Georgia Institute of Technology. His graduate research focused on piezo-hydraulic actuation systems — using two-stage amplification of piezoelectric stroke to drive practical loads such as helicopter rotor blade trailing edge flaps.

Subsequent publications in the SPIE Smart Structures and Materials proceedings extended this work into computational modeling of ferroelectric domain structures and miniature piezo-hydraulic pump development. Today Scott applies the same systems-thinking approach to commercial food automation as an engineer at Chick-fil-A.
