Use glass fracture patterns to explain how to sequence events that occurred to form the broken glass. Find Volume of glass. It found in many shapes size colour and types.
Glass is reasonably hard transparent or translucent material composed of fused inorganic materials primarily of silicon dioxide sand Glass is super cooled liquid amorphous in nature. Form on the side opposite the point of impact. SUSPEND the glass in water.
Day-1-Students will first watch the video lecture or power-point glass analysis and take summary notes. Its fracture toughness K IC value is only 1 MPa m. A geomechanical understanding of these properties.
The cracks will appear radiating outwards from the point of impact making a star shaped fracture known as radial fracture. Stack the series of activity pictures on the right with dashed lines to where the activity takes place ACTIVITY 14-1 GLASS FRACTURE PATTERNS Objectives. Fracture patterns can provide clues about the direction and rate of impact.
Due to its irregular atomic structure when the glass is broken it produces a variety of fracture patterns. - Which direction did the break travel. As the expert in glass you told the.
