The '''Misnay–Schardin effect''', or '''platter effect''', is a characteristic of the detonation of a broad sheet of [[explosive]].

== Description ==
Explosive blasts expand directly away from, and [[perpendicular]] to, the surface of an explosive. Unlike the blast from a rounded explosive charge, which expands in all directions, the blast produced by an explosive sheet expands primarily perpendicular to its plane, in both directions. However, if one side is backed by a heavy or fixed mass, most of the blast (i.e. most of the rapidly expanding gas and its kinetic energy) will be reflected in the direction away from the mass.<ref>''Practical Bomb Scene Investigation'', James T.

== Uses ==
The Misnay–Schardin effect was studied and experimented with by explosive experts József Misnay (sometimes spelled Misznay incorrectly), a [[Hungary|Hungarian]], and [[Hubert Schardin]], a [[Germany|German]], who initially sought to develop a more effective antitank mine for [[Nazi Germany]].<ref>{{Cite web |title= Misnay József |publisher= Haditechnikai Intézet |url= https://haditechnikaiintezet.hu/misnay-jozsef |access-date=2024-01-12 |language= hu}}</ref><ref>{{Cite journal |title=

The later [[AT2 mine|AT2]] and [[M18 Claymore mine|M18&nbsp;Claymore]] mines rely on this effect.<ref>''Jane's Mines And Mine Clearance 2006/2007'', Colin King, Jane's Information Group, 2006, p.&nbsp;31.</ref>
