Resistive method for measuring the disintegration speed of Prince Rupert's drops

Abstract

Abstract.We have successfully applied the resistance grid technique to measure the disintegration speed in special type of glass objects, widely known as Prince Rupert's drops. We use a digital oscilloscope and a simple electrical circuit, glued to the surface of the drops, to detect the voltage changes, corresponding to the breaks in the specific parts of the drops. The results obtained using this method are in good qualitative and quantitative agreement with theoretical predictions and previously published data. Moreover, the proposed experimental setup doesn't include any expensive equipment (such as a high-speed camera) and can therefore be widely used in high schools and universities.

Prince Rupert’s Drops: An analysis of fragmentation by thermal stresses and quench granulation of glass and bubbly glass

“…The exact mechanism responsible for crack propagation in PRDs ( 29 , 30 ) and more generally, in glass fracture ( 31 ) remains an active topic of research. A theoretical foundation is supplied by Griffith crack theory and the broader field of fracture mechanics ( 32 , 33 ).…”

HU - The Big Pop Cosmogenesis Equation of State

“…HU proposed that the Universe surfs the inner dilation layer which is the actual 4D Entropic Explosion. The entropic explosion is analogous to Prince Rupert Drop [41][42][43], in many ways.…”

Spontaneous Fracture in Thermally Strengthened Glass - A Review and Outlook

“…creating small blunt glass fragments, but energy will also be released as sound, heat generation and kinetic energy (accelerating the fragments) [2,3,5]. Thermal strengthening of glass has been reviewed extensively by several authors over the years [1][2][3][7][8][9] and the first case of thermal strengthening is the so-called Prince Rupert's drop that the well-known Hooke observed in 1665 [10,11], a phenomenon which still receives scientific attention [12][13][14]. The fact that thermally strengthened glass fracture into small blunt pieces [15] has the advantage that it is less dangerous and there is a standard for "fully" thermally strengthened glass or frequently called "safety" glass EN 12150 [2,3].…”
