Latest Patents

Hossain’s patents address ways to measure effective toughness and analyze fracture progression in materials.

- **Systems and Methods for Determining the Effective Toughness of a Material and for Implementing Materials Possessing Improved Effective Toughness Characteristics.** This invention describes determining a material’s effective toughness by causing a crack to propagate at a prescribed, maintained velocity and direction. The energy release rate is measured during propagation, and the material’s effective toughness is defined as the maximum measured value. The methods can also support the development of materials with improved effective toughness.

- **Measurement of Fracture Toughness of Heterogeneous Materials.** This invention describes a rail-and-roller system that applies gradual force to a specimen, producing steady fracture development. A camera records the progression, and mathematical analysis is used to determine the material’s effective fracture toughness.
