Glass fracture patterns worksheet answers

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. Concentric Fracture - A crack in a glass that forms a rough circle. 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. A glass association is defined as two or more glass samples that can be fracture fitted together, or that exhibit indistinguishable observable properties and/or range overlap in all measured properties. ... and discrimination of sheet and container glasses by inductively coupled plasma-atomic emission spectrometry and pattern recognition ... Explain two different methods to determine the direction of the bullets based on glass analysis. d. If you examined the actual glass, could you determine who was telling the truth: Henry or Ralph? Explain your answer. 5. Examine the diagram of the glass fracture patterns below. Three different impacts resulted in the breaking of the glass.

Glass fracture patterns worksheet answers. Fracture patterns are unique. Fracture features in a piece of glass reflect the nature of the glass and the direction of travel and velocity of the breaking object. Glass fracture examinations can provide information as to the direction of the breaking force and the sequence of multiple impacts. Glass Fracture Patterns Fracture Patterns A special type of glass made by substituting metal oxides for silica Used in car head lights, glasses used in labs, and thermometers by: Anya Byrd Order of Penetration It's relatively easy to find out the order in which the glass was fractured. You look at the radial fractures. Glass analysis includes determining the type of glass based on glass fragments. However, the entire fractured pane or window can be helpful when determining direction and sequence of force. Glass type determinations: This type of determination compares a known sample to a glass fragment to see if the two samples came from the same source. hyperlinked version of this worksheet by going to the following website - rvanwie.wikispaces.com.

Explain your answer using the terms tension and compression. 3. Tempered glass is also known as safety glass. One of the main uses of this type of glass is for car windshields. When impacted, safety glass fractures differently than window glass. Analyze the pictures of safety and window glass below. (If you have Fracture Patterns in Broken Glass Glass has some flexibility. When stretched too far, fracture lines appear and the glass may break. Fracture patterns can provide clues about the direction and rate of impact. Compression Tension Glass fracture patterns worksheet answers. Plain glass will yield true radial and concentric fractures which are similar to the sketch above. Although the examination of a single crack may indicated a degree of similarity the overall composition and shape of cracks in these two types of glass differ significantly. Glass Fracture Patterns. Glass has a certain degree of elasticity. ... Explain the directions for the lab experiment. Allow the students some time to complete the worksheet and the density equation (approximately 10-15 minutes). Discuss the questions from the worksheet as a class. ... The students' answers will vary depending on the glass ...

These lines set the boundaries for further fracturing by following shots. Radiating fracture lines from a second shot stop at the edge of fracture lines already present in the glass. • Fracture patterns are unique; Pieces from the broken glass pane or hole often show marks that are characteristics of the type of injury and direction of force.

Step. 3: Fracture Patterns • Broken glass analysis is forensically important to the reconstruction of events in a criminal act • Analysis can include: • The sequence of the fractures -order of events • The direction of the force which caused the fracture - did the break occur from the inside or outside • The identity (type) of a small piece of glass -soda 1. Use glass fracture patterns to explain how to sequence events that occurred to form the broken glass. 2. Analyze glass fracture patterns and determine the order of the breaks in the glass. 3. Distinguish the differences between fractures formed in tempered or safety glass and the fractures formed in window glass.
