Discussion Overview

The discussion revolves around the effects of blast simulations, specifically focusing on the applicability of a particular online tool for visualizing blast effects from different types of detonations, including nuclear and non-nuclear sources such as IEDs. The scope includes technical clarification and exploratory reasoning regarding the tool's capabilities and limitations.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires whether the HYDESim tool is limited to nuclear blasts or if it also accounts for other types of explosions, such as IEDs.
  • Another participant points out that the HYDESim tool specifically maps overpressure radii from ground-level detonations and does not include other effects like thermal damage or fallout.
  • A further response clarifies that while IEDs typically have minimal explosive capacity and focus on shrapnel damage, some larger IEDs may have more significant yields, but these may not be accurately represented by the HYDESim maps.
  • It is suggested that a mining handbook could provide more reliable information for blast predictions, particularly for non-nuclear explosions.

Areas of Agreement / Disagreement

Participants express differing views on the applicability of the HYDESim tool to non-nuclear blasts, with some suggesting it may not scale well for IEDs and others indicating that the tool is primarily designed for nuclear detonation effects.

Contextual Notes

Limitations include the tool's focus on idealized conditions without accounting for terrain, urban density, or other environmental factors that may influence blast effects.

Hi all,
Am researching on the blast simulation. So tout of adding d effect of blast in my presentation in order to give audience the feel of how large the effect can be.
I will use the following site
meyerweb.com/eric/tools/gmap/hydesim.html
Can you please throw some light on whether the given map includes the effect due to nuclear weapon blast only OR due to any other kind of blast too?

Thank you in advance,
TheSymbol

I suggest you study the linked website more closely. Directly under the map it states:

HYDESim maps overpressure radii generated by a ground-level detonation; these radii are an indicator of structural damage to buildings. No other effects, such as thermal damage or fallout levels, are included in this tool. Note that the displayed rings are "idealized"; that is, no account is taken of terrain, urban density, ground type, weather conditions, and so on.
 
Thank you for the reply again.

But my doubt is not about the effect. I wanted to know whether the detonation like IEDs can also be considered here, which do not fall under the Nuclear category.

Regards,
TheSymbol
 
IEDs usually have minimal explosive capacity and rely on shrapnel damage rather than blast.
Of course, there are IEDs such as for OklahomaCity blast using several tons of fuel oil and ammonium nitrate, but even they have less than a 0.01kt yield, where the HYDES maps may not scale well.
A mining handbook might be more helpful, as reliable blast prediction is of importance there.
 
Thank you for the reply :smile:
