These fractures originate from the surface opposite to that of the force applied. Fundamentals Investigations Chapter.

Unfortunately the absence of radial or concentric fracture lines prevents.

. Concentric Fracture - A crack in a glass that forms a rough circle. Related Questions Litigation Flowchart By Jody Cooper. And search more of iStocks library of royalty-free stock images that features Backgrounds photos.

Often it is difficult to determine just from the size and shape of a hole in glass whether it was made by a bullet or by some other projectile. The next step is to figure out which side of the fragment was facing in and which side was facing out. The first shots radial fractures will extend completely while the subsequent shots radial fractures will be stopped or cut off as they come into contact with prior fractures.

Concentric fractures connect the radial fractures in a pattern similar to a spider web. Radial Frac tures. This difference is a result of the glass bending away from the side of impact and the first radial fracture occurring on the rear side after the limit of stretching elasticity has been reached.

Download this Broken Glass Concentric Glass Fracture photo now. Concentric cracksare fractures forming in an approximately circular pattern around the point of impact. Concentric circles form on the same side of the glass as the point of impact.

Radial Fracture - A crack in a gloss that extends outward like the spoke of a wheel from the point at which the glass was struck. From the measurement it was noted that the hole diameter values lies between 41 and 67 mm. You can visualize these constraints by color if you change the Guide Geometry to Constraint Network.

When a projectile ie. Concentric Fracture - A crack in a glass that forms a rough circle. The concentric glass fractures are the secondary fracture and occur after radial fracture.

Formation of Radial and Concentric Fractures in Glass Screencast By Ronald Groffy in this screencast learners examine the formation of radial and concentric fractures as an object breaks a pane of glass. For more information see the Constraints help page. O Then fractures form in the shape of concentric circles on the same side of the impact.

On concentric fracture lines the opposite condition will be found with the well-developed and individually distinct portions of the fracture lines appearing on the front or impact side. When glass breaks most of the glass falls inward. This leads to series of concentric circles around the point of contact known as concentric fracture.

A bullet or rock hits the glass it will form two distinct types of fractures. Previously Harshey et al. 4r rule- determining side of impact ridge lines on radial fractures are at right angles to the rear side opposite the.

They are usually in straight segments that terminate in an existing radial crack. These fractures are known as primary fractures. The radiating lines are appropriately known as radial fractures and the circular lines are termed concentric fractures.

DIFFERENT TYPES OF GLASS FRACTURES. However the tiny shards produced in the formation the concentric fractures spray backwards towards the person wielding the weapon or tool. The constraints between radial fractures will match your Radial Color dark blue and the constraints between concentric fractures will match your Concentric Color light blue.

Contaminants or residues from the inside surface will feel different than the outside surface and are helpful in determining the sides. This was demonstrated by firing a firearm at close range into a pane of glass with a white cotton pad located immediately behind it. This study was performed to analyze the multiple glass fracture.

These tiny bits of glass can get caught in the hair and clothing of a person near the point of impact. Cone or crater Hertzian cone is a funnel-shaped area of damage caused by a high-velocity impact. Radial Fracture - A crack in a gloss that extends outward like the spoke of a wheel from the point at which the glass was struck.

Even after washing tiny fragments of glass can. Why Radial and Concentric Fractures Form o Impacted glass is compressed on the side it is hit. Radial fractures are similar to the spokes of a.

If the force continues even after the radial fracture the tensile stress develops on the side where the force was applied. There is another terminology that is known as cone fracture observed to be caused by a penetration of the high velocity projectile such as a bullet. Analyzed the pattern of glass fractures that were made by the air rifle on the glasses of different thicknessIn this approach a special aspect of glass coating with Sun.

A crack or fracture in a gloss that spreads outward or radiates from the place where the glass was struck Point of impact like the spoke of a wheel. The concentric-like fracture lines often causing physical dislocation of the glass from the pane are created after the radial fractures. 3R Rule shows radial cracks at a right angle to the rear of the applied force.

O It will stretch on the opposite side of the glass and the tension there will radiate breaks in the glass outward from the point of impact.
