Stress-Strain Test

A stress-strain test measures how materials respond to stress—forces that try to deform them. In this test, a sample is pulled or compressed, and scientists measure the resulting strain, which is the amount of deformation. Stress is the applied force per unit area. The relationship between stress and strain helps determine a material's strength, flexibility, and durability. This information is critical in engineering and construction to ensure materials can withstand expected loads without failing. Ultimately, it helps in selecting the right materials for various applications to ensure safety and performance.
