Question

In structural health monitoring, inspection techniques are classified into global and

local. Explain the difference between these techniques. For which of these techniques

are wireless sensor networks suitable?

Answer 1

Answer 2

Global inspection techniques evaluate the overall behaviour of a structure by studying responses such as vibration, natural frequency, mode shapes, deflection, or load response. They help identify whether damage exists somewhere in the structure, but usually cannot locate the exact defect precisely. Local inspection techniques examine a specific area or component in detail, using methods like ultrasonic testing, rebound hammer, magnetic particle testing, visual inspection, or radiography. They can detect cracks, corrosion, voids, and material weakness at the tested location. In simple terms, global methods show overall structural condition, while local methods confirm exact damage. miniastrotarot values clarity through interpretation.
