So you do not need to waste the time on rewritings. discontinuities that are open to the surface where the penetrant has been applied. 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. Glass fracture mechanism: A rethinking, Journal of Forensic Sciences (1986) 31:818-824.
Glass fracture examinations can provide information as to the direction of the breaking force and the sequence of multiple impacts. In: Forensic Science Handbook. Causes of cracks The most common causes of cracking are: Ground movement (beneath foundations) caused by clay shrinkage, land slip, vibration, subsidence, settlement, heave, sway, and so on.

The first step in this method is to find radial fractures that are within the first concentric fracture. Radial fractures are similar to the spokes of a wheel. Extreme care should be taken to prevent further breakage of the glass during any phases of packing, shipping, or unpacking of glass shards.

Not all foundation cracks are necessarily bad. This rule enables an examiner to determine readily the side on which a window or pane of glass was broken. Nonoptical Physical Properties of Glass (3 of 5) Surface contaminants Contaminants show the presence of impurities. When a projectile strikes glass, it creates ridges called conchoidal fractures along the edge that are visible in profile. I may not have millions, but I have peace, things look much richer. Nonoptical Physical Properties of Glass (4 of 5) Thickness The thickness of glass must be measured with a high degree of accuracy. Mention is made of a "3R" rule, indicating that radial fracture surfaces possess arcs at right-angles to the rear surface of the window. The sequence of multiple impacts can be deduced when the cracks caused by a subsequent impact terminate at previously formed cracks.

Forensic Examination of Glass Evidence: An Overview (1 of 2) Goals in examining glass evidence: Determine the class to which the glass belongs Individualize the glass to one source, Forensic Examination of Glass Evidence: An Overview (2 of 2) Two samples are needed for forensic analysis: Glass from the crime scene Glass on items belonging to the suspect Compare characteristics of the samples: Color, fracture pattern, scratches, striations from manufacturing, unevenness of thickness, surface wear, surface film or dirt, weathering patterns. 4. RIB FRACTURE/ STRESS LINE: the edges of broken piece of glass bears a number of curved lines termed as stress lines. These stress lines are tangent to the one side of the glass and perpendicular to other side. They are always perpendicular to the surface at which the crack is originated. Thornton, J.
