Specific to blast loading, bond shear tests between carbon fiber reinforced polymer (CFRP) strips and concrete have not yet been reported in literature, to the best knowledge of the authors. Given the high potential of strengthening concrete with CFRP to increase blast resistance, it is necessary to better understand the dynamic interaction between concrete and CFRP under blast impulse. This article presents a new experimental setup ...

This paper deals with the non-linear dynamic behavior of thin Aluminium
plates subjected to blast loading. Aluminium plates with grade EN AW-1050A-H24
are studied. The square specimens have an area of interest of 300*300mm2 and
a thickness of 2.5mm. The blast loading is generated using free air blast (FAB)
and explosive driven shock tube (EDST). A numerical finite element model (FEM)
using the commercial software LS-DYNA ...

Assessment of the structural dynamic response caused by an explosion is complex due to the high velocity impact, the transient nature of the deformation and the interactions between the structure and the pressure wave. This paper deals with full-field measurements of aluminum plates under free air blast loading conditions. Forty grams of explosive material C4 is detonated at a stand-off-distance of 250 mm and two synchronized high-speed cameras ...

This paper presents nonlinear finite element (FE) simulations to predict the structural behavior of simply supported reinforced concrete (RC) slabs retrofitted with carbon fiber reinforced polymer (CFRP) as externally bonded reinforcement (EBR) and subjected to the blast loads in order to evaluate the effectiveness of using the CFRP strips as EBR for blast protection. The objective of this paper is to develop detailed numerical models in order ...

The dynamic behaviour of structures under
blast wave loading is increasingly studied due to the rising
risks of intentional and accidental explosions and the
development of new protective technologies and methods.
To ensure the efficiency of these protective measures, the
identification of the material behaviour under blast loading
is of utmost importance. This paper investigates the
feasibility of the ...

In this paper, the failure of a pultruded glass fiber reinforced composite tube subjected to axial impact load transmitted by a small attached mass exposed to blast load is discussed. A numerical simulation is developed with LS-DYNA and is validated with experiments carried out on a ballistic pendulum by comparing the transmitted impulse by the explosive and crushed distance of the composite tube. The air blast is simulated using Eulerian ...

This work investigates the use of blast loadings and inverse modeling for the identification of the strain rate hardening model parameters of fibre reinforced polymers. An experimental setup allowing the generation of known and predictable blast waves, leading to repeatable dynamic response in composite plates and the measurement of the displacement and strain fields, is developed. The dynamic response of the plates is measured by means of ...

The need for efficient blast loading tools is increasing with the development of new protective techniques. Among these tools, one can cite the use of an explosive-driven shock tube (EDST). The purpose of the present study is to define analytical equations to predict incident and reflected pressure and impulse generated at a laboratory scale EDST end in terms of the tube length, the tube diameter, the explosive mass, and the stand-off distance. ...
