Latest Patents

Antonio holds a patent for a method aimed at improving the reliability of brittle materials through the creation of a threshold strength. This method involves producing reliable, flaw-tolerant brittle materials by incorporating layers under residual compression on the surface and throughout the bulk of the material. These layers serve to trap and contain the propagation of catastrophic cracking. The residual compression within these layers reduces the stress intensity of the cracks, effectively causing them to arrest until further loading is applied. This stable, subcritical crack growth mode persists with increased loading until the applied stress is sufficient to drive the crack completely through the compressive region, leading to failure. The architectural design of the compressive layers dictates the exact stress level needed for this process, allowing for the material to be engineered with any desired minimum strength. This results in a truncation of the strength distribution, virtually eliminating the probability of failure below this minimum value, thereby providing a threshold strength. Consequently, sensitivity to flaws that would typically cause catastrophic failure at stresses below this threshold is eliminated. Furthermore, the potential exists for the complete elimination of strength variability, enhancing reliability through the creation of nearly deterministic strengths by increasing the threshold strength above the stresses at which failure usually initiates from intrinsic flaws.
