In mechanical engineering, resistance to external forces is stress. The stress that is 'stacked' inside the material is called the residual stress. We often say "Oh! It's stressful." It's a very engineering expression to say. Eventually, the accumulated stress will exceed the level that can be sustained, and the material will break off. There is no way to avoid the accumulation of stress. It is ..
Deformation occurs when any material is applied to a load, and breakage occurs when the deformation is too large. Sometimes the fracture occurs at a much lower strength, even though the breaking strength that the material can endure is determined. It happens at very unpredictable timing. Such a load is called fatigue load. Such fracture is caused by fatigue. So fatigue is dangerous. This is beca..
All materials have their own areas of resistance. The strength at which the material breaks is called the breaking strength. And yield strength is the strength at which material destruction begins. Deformation due to loads less than the yield strength can be recovered. This ability to recover is called 'elasticity'. The best elastic material is rubber. It has good recovery ability. The material ..
