What happens if the limits of stress and strain are exceeded in a structure?

If the limits of stress and strain are exceeded in a structure, it can lead to material failure, which may manifest as deformation, cracking, or complete structural collapse. This occurs when the material reaches its yield strength, transitioning from elastic to plastic behavior, resulting in permanent damage. In extreme cases, such as in overloaded structures, catastrophic failure can happen suddenly, posing significant safety risks. Proper engineering design incorporates safety factors to prevent such occurrences.
