Stress Analysis is a method used in engineering and materials science to determine how materials respond to external forces. It involves calculating the internal forces, moments, and deformations that occur when a structure or component is subjected to loads. This analysis helps ensure that materials can withstand the stresses they encounter without failing. Engineers use various techniques for Stress Analysis, including Finite Element Analysis (FEA) and analytical methods. These techniques allow them to predict how structures will behave under different conditions, ensuring safety and reliability in designs. By understanding stress distribution, engineers can optimize materials and structures for better performance.
