Deformation and fracture of cylindrical shells made of glass-epoxide under an internal pulse load

Criterion for Selecting Composite Materials for Explosion Containment Structures (Review)

“…The applied specific explosive load is characterized by the parameter ξ ∼ m HE /M (m HE is the mass of the explosive). Taking into account that I ∼ m HE [15],…”

“…Indeed, following [13] and using the short shock hypothesis [15], we find that if a centrally symmetric pulse I acts on a ring shell element of mass M , its initial kinetic energy I 2 /2M at the end of the extension stage is converted to the potential elastic-strain energy of the element, i.e.,…”

Dynamic Strength of Fiber Glass Shells

“…One has not observed influence of the scale change on strength and deformability of the shells, which are similar geometrically and up to 4.4 times differ in sizes. Absence of the scale factor of the strength Article published online by EDP Sciences and available at http://dx.doi.org/10.1051/jp4:1997389 drop having energetic nature [3] can be explained by similar structure of the composite and its invariability in the material of shells having different diameters of the basic element that is fiber glass [1, 3,41. In comparison with steel shells [2] fiber glass shells have some advantages associated with variations in energy-intensity (i.e. energy absorption under deformation) of these materials under similar specific loads 6 (where 5 -ratios between the TNT equivalent of explosion and mass of the shell ).…”
