Total Energy of Hemi-cylindrical Shells Subjected to Blast Loading: Comparison with Theoretical Method
Abstract
This study presents the total energy response of the hemi-cylindrical shell with a steel material under the external blast loading by employing both theoretical approach and numerical simulation. Analytical approach demonstrate that the total energy contributed from blast is inverse proportional to the thickness of shell. It is proportional to the inverse tangent function applied by the ratio of denotation coordinate over the radius of shell. Moreover, to verify the theoretical inference, several numerical simulations were carried out. Those result agree well.
