Why did we do it?
-
Need for VHCF crack growth up to 750 Hz
-
Need for customization
-
Weak customer support from legacy supplier
-
Multiple test segments can run unattended
-
Automated crack segment marking-heat tint/stress ration (Material and geometry dependent.)
-
Cyclic fatigue allowing PD or compliance measurements with stop criteria as a percentage change over initial PD or compliance value - helpful when developing PD or compliance to crack length solutions and un-attended monitoring.

WHO WE ARE
RAYMOND "KEITH" KERSEY
Founder, Advanced Fracture Mechanics Associates
SInce 1990, Keith Kersey has developed advanced methods in a multitude of mechanical testing techniques. Kersey furthered the development of two groundbreaking advancements known as Adjusted Compliance Ratio technique (ACR) and the Master Curve Approach by applying the technique to seven materials from room temperature to 1400F, 760C. This work is currently under peer review to be published. These methods correct the inaccuracies of decades of test data generated previously and are the premise of the competitive advantage that AFMA has been founded.
EDUCATION
Master's Degree in Mechanical Engineering
University of Hartford
RICHARD PETTIT
Founder, FractureLab
Dr. Pettit is a registered professional engineer in the state of Utah, and is the founder and Managing Director of FractureLab LLC, a consulting and specialty laboratory services firm in the fracture mechanics field. He is the inventor and developer of the first Flat Bottom Hole specimen and the piezoelectric test rigs used at FractureLab, and an electrothermal crack-tip marking system among several other innovative R&D efforts involving high-frequency crack growth test software development, threshold testing, laser fatigue testing and laser control for additive manufacturing. He is also a founding member of the Integrative Material Design Center (iMdc) at WPI.
