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. 7 rows You can visualize these constraints by color if you change the Guide Geometry to Constraint Network.

They are usually in straight segments that terminate in an existing radial crack.

. 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. Concentric cracksare fractures forming in an approximately circular pattern around the point of impact. Log in Sign up.

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. For instance a small stone thrown at a comparatively. Concentric Fracture - A crack in a glass that forms a rough circle.

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. Cone or crater Hertzian cone is a funnel-shaped area of damage caused by a high-velocity impact. This learning object describes the equipment and supplies needed to document bloodstain patterns.

Start studying Glass Fracture Patterns. Concentric fractures connect the radial fractures in a pattern similar to a spider web. Contaminants or residues from the inside surface will feel different than the outside surface and are helpful in determining the sides.

Fractures radiating from the point of. 4r rule- determining side of impact ridge lines on radial fractures are at right angles to the rear side opposite the. Concentric circles form on the same side of the glass as the point of impact.
