Structural Degradation
The progressive deterioration of a system's structural integrity due to various physical, chemical, or environmental factors over time.
Structural Degradation
Structural degradation refers to the gradual decline in the physical and functional properties of materials, structures, or systems over time. This universal process affects everything from building materials to biological systems, presenting significant challenges for engineering and maintenance.
Core Mechanisms
Several key processes contribute to structural degradation:
- Physical Deterioration
- mechanical stress and fatigue
- weathering effects
- Vibration and movement
- thermal cycling
- Chemical Degradation
- corrosion processes
- oxidation
- Chemical reactions with environmental substances
- material decomposition
- Environmental Factors
- moisture damage
- UV radiation exposure
- temperature fluctuations
- biological degradation
Prevention and Mitigation
Preventive Measures
- Implementation of proper design principles
