Application of Raman Spectroscopy in Mechanical Engineering

In Mechanical Engineering, Raman spectroscopy analysis is a non-destructive technique to study material composition and stress at the microscopic level. It helps in identifying chemical bonds, molecular vibrations, and structural changes in metals, polymers, and composites. Engineers use it for failure analysis, quality control, and monitoring residual stress. Raman spectroscopy also supports advanced manufacturing and nanotechnology applications. Its precision enhances material performance and mechanical reliability.
