Structural integrity is a research area that focuses on the ability of a structure to withstand its intended loads without failing or deforming excessively. This field involves studying the behavior of different materials and designs under various external forces and conditions to ensure the safety and reliability of structures such as buildings, bridges, aircraft, and spacecraft. Researchers in this field often use analytical and experimental methods to analyze the stress, strain, fatigue, and failure mechanisms of materials and components in order to optimize design, maintenance, and performance. The goal of structural integrity research is to ensure the long-term safety and durability of structures while minimizing the risk of catastrophic failures.
