Abstract

Using the energy of explosion, a print of the picture "Medieval mine" onto an aluminium plate was made. This is one version of a technique called Detonography. It has been introduced and developed by Evelyn Rosenberg with a number of her colleagues, based on the "Munroe effect". To determine the optimal parameters of explosive performance and supporting materials, a large number of laboratory testing has been made on smaller samples.

SAŽETAK

Koristeći se energijom eksploziva napravljen je otisak slike srednjovjekovnoga rudnika na aluminijsku ploču. Riječ je o verziji tehnike koja se zove detonografija. Uvela ju je i razvila Evelyn Rosenberg u suradnji s nekoliko kolega, a na temelju Munroeva efekta. Za odreðivanje optimalnih parametara učinka eksploziva i pratećih materijala izveden je velik broj laboratorijskih ispitivanja na manjim uzorcima.

1. Introduction

The use of explosives as a high-energy source in the metals field and energetic materials has developed from an interesting curiosity to metal working reality, with extensive possibilities now existing in a wide range of industries. Explosive metal working operations now include the forming, sizing, flanging, engraving, compacting, welding, hardening, and cutting of metals (Rinehart and Pearson 1963). Detonography as a blast-produced art has been developed by Evelyn Rosenberg with several of her colleagues, based on the "Munroe effect", which is also known as the "von Foerster effect" in Europe (Kennedy 1990). It acts as a perfect medium for transferring pictures into a new form of art (Rosenberg 2013). To test this phenomenon, it has been decided to make a print of a less complex picture "Medieval mine" onto an aluminium plate. To achieve that, a number of different parameters had to be determined by conducting laboratory testing on smaller samples.

The final product is exhibited within faculty walls.

2. Background

The history of shaped charge will bring us from Franz von Baader (1792) to Charles E. Munroe who rediscovered the hollow cavity i.e., the unlined shaped charge (Walters and Zukas 1989). Charles E. Munroe, professor of chemistry at Columbian University, in conducting his experiments at the Naval Torpedo Station in 1888, noted that explosive waves tended in certain cases to reinforce each other. His discovery was made quite by accident. Professor Munroe used...
