Abstract In the current century, building protection is very important in the face of terrorist attacks. The old buildings in Europe are not sufficiently resilient to the loads produced by blasts. We still do not fully understand the effects of different explosives on buildings and human bodies. [1–3] Computing blast loads are different from that of traditional loads and the material selection rules for this type of impact load are diverse. Historical and old buildings cannot be protected simply by new walls and fences. New ways need to be found to improve a building’s resistance to the effects of a blast. It requires sufficiently thin yet strong retrofitted materials in order to reinforce a building’s walls [4–6].

A theoretical model is developed to investigate the mechanical behavior of closely packed carbon nanoscrolls (CNSs), the so-called CNS crystals, subjected to uniaxial lateral compression/decompression. Molecular dynamics simulations are performed to verify the model predictions. It is shown that the compression behavior of a CNS crystal can exhibit strong hysteresis that may be tuned by an applied electric field. The present study demonstrates the potential of CNSs for applications in energy-absorbing materials as well as nanodevices, such as artificial muscles, where reversible and controllable volumetric deformations are desired.

The development of adequate protection against head injury requires a thorough knowledge of the mechanics of trauma to an unprotected head. Impact to multi-layered spherical head models are analyzed with an elastic skull, elastic tables and elastic-plastic diploe skull, and elastic tables and crushable foam diploe skull. All models have a hydrodynamic brain model. The energy absorbing skull models yield highly attenuated and smoothed tensile pressure peaks in the brain as compared to the elastic skull model. The generality of the solution technique would readily permit extension of the analyses to investigate impact to a head protected by a multi-layered helmet.
