Strain
In space and astronautical engineering, strain refers to the deformation of a material under the influence of an external force or load. Strain can occur in various components of a spacecraft, such as the structure, thermal protection system, or propulsion system, due to factors such as launch vibrations, thermal cycling, or engine thrust. Strain can be measured using strain gauges or other sensors, and it is important to monitor strain levels to ensure the structural integrity and performance of the spacecraft. Excessive strain can lead to material failure, which can be catastrophic in space missions. Therefore, engineers must design spacecraft components to withstand the expected strain levels and perform rigorous testing to validate their designs.
