Latest Patents

Hsueh’s patents address the measurement and improvement of material toughness.

“Systems and Methods for Determining the Effective Toughness of a Material and for Implementing Materials Possessing Improved Effective Toughness Characteristics” describes a method for determining a material’s effective toughness. The method causes a crack to propagate at a prescribed, maintained velocity and direction, measures the crack’s energy release rate, and defines effective toughness as the maximum measured value. The patent also describes implementing materials with improved effective toughness.

“Measurement of Fracture Toughness of Heterogeneous Materials” presents a method for measuring effective fracture toughness. A rail-and-roller system applies gradual force to a specimen, producing steady fracture development that a camera records. Mathematical analysis of the recorded progression is then used to determine the material’s effective fracture toughness.
