Nondestructive Testing of Metals Using Second Harmonic Generation ID: 2013-046

A novel method for detecting strain and dislocations in metals through Second Harmonic Generation, offering a preemptive approach to identifying potential equipment failures.

Technology Overview

This technology, developed by James E. Patterson and Shawn Christopher Averett at Brigham Young University, employs Second Harmonic Generation (SHG) to nondestructively test and identify dislocations and strain in crystalline materials. By utilizing SHG, this method can detect plastic deformation in metals, potentially before such deformation leads to equipment failure. This technique integrates fiber-optic technology to enhance commercial viability, marking a significant advancement in the field of material testing and quality control.

Key Advantages

• Nondestructive testing allows for early detection of potential failures
• Cost-effective solution for industries requiring high reliability
• Utilizes fiber-optic technology for enhanced application and efficiency
• Applicable to a wide range of crystalline materials beyond metals
• Improves upon existing methods by offering practical, real-world application

Problems Addressed

• Early detection of plastic deformation in metals
• Prevents equipment failure through preemptive identification of material weaknesses
• Offers a more efficient and cost-effective quality control process
• Reduces the risk of unexpected downtime and maintenance in critical applications

Market Applications

• Quality control for manufacturing industries
• Maintenance and safety checks for military equipment
• Aerospace and automotive industries for material integrity assessment
• Infrastructure monitoring for early signs of wear and tear
• Research and development in material science
