Void Analysis

Nondestructive Inspection of Subject

Nondestructive Inspection is a technology that detects hidden damages and defects on an object without breaking it by either radiating radiation and sonic wave on a material, or flowing current or magnetic flux through the surface.

This technology is utilized for various purposes from analysis of plain crash to examination of bulding and plumbing.

There are types damages and defects detectable by nondestructive inspection.

e.g.

• Dimensional error,warping, and cracks of dicast products.
• Porosity such as pit and blowhole, types of weld defect
• Matrix cracks that occurs in composite materials such as carbon fibre-reinforced plastic and is caused by the enlargement of cushioning materials
• Plastic deformation of rubber and so on

Among the types of defects shown above may be hidden inside, which requires having a look inside the subject.

Void Analysis (Sold Separately)

Void analysis detects "voids" from the images and classify them into groups, which are "labled" separately with different colours.

By making the original greyscale image transparent or translucent, voids expressed in different colours appear. The number, volume, and size of the void are displayed below.

The size, distribution, and ratio of the cracks and bubbles in the objects becomes apparent after the Void Analysis.

The result could be exported as parameters numerical values in a csv file.
