The paper presents experimental and analytical studies on axial compression of aluminium spherical shells having Radius/wall thickness (R/t) ratios between 23 and 135. Quasi-static compressive load was applied centrally and with offset through a indenter having diameter of 22mm. Testing was carried out on an INSTRON machine having 250T capacity. Shells having different radius and wall thickness were...
Summary form only given. Intense laser ablation induced shocks have been found use in the field of high pressure and high energy density physics studies viz. equation of state (EOS) measurements, phase transformations, understanding astrophysical high density plasma phenomena etc. Several megabars of pressures can now be generated, under laboratory conditions using modest laser intensities. To achieve...
