What type of materials?

Elizabeth, what types of materials are these? The article says they're a new class, but does that mean metals, plastics, composites, nanocomposites, or something else?

I think William raised a good point. If these artillery shells are 5x more lethal, does that mean 5x the explosive force? Whatever the percentage or factor, it's greater explosive force which means they're likely to be more dangerous to store, as well as to deploy.

Reactive material artillery shells.

I would be concerned about the stability of the materials under various conditions. Unstable ordinance just sounds like it would be really unpleasant. The reason for this concern is that it seems to me that materials that are able to explode would be a bit more reactive, and thus less likely to be completely stable. But perhaps there is another answer.

I agree about the emotional response--that's why I prefer "x times" to "x%."

Like the Ironman Ammo Carrier (above), it should ease the burden of material needed to wage war.

Jhankwitz, you are right. Every year government is spending billion of USD for military R&D inorder to strengthen the national security and weapon systems. I think the same technology can also be use for common peoples benefit also. For example, the light weight materials using in space craft can be used for making artificial limbs etc.

Thanks Ann.  I understand the math.  I was just making an observation about the emotional response to "500 percent more lethal". 

Mining work is a possibility but, as you mentioned, I don't see any advantage over current technology for that particular industry.

I agree, Ann. I can't imagine any non-military applications for this. It's designed, not just to explode, but to wreac havoc when it does.

500 percent more lethal just means 5x more lethal. Although that's a lot, considering the fragments will release both kinetic and chemical energy. The only non-military use I can imagine is for the other apps of explosives, such as mining work, although I don't see what chemical energy will bring to that effort. It would be interesting to know what chemicals are involved.

It's unfortunate that the results of this research will be limited to military applications.  It would be nice if it could spill over into non-military applications.

When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
The machine is claimed to be the largest and most powerful electric pipe-bender on the market, exerting nearly 500,000 lb-ft of torque.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
This consulting firm has put together a report detailing the growing biomimicry design field in the US and around the world, from naturally bacteria-repelling surfaces to keratin-inspired polymers.
