| Abstract: | Aim To study the deformation effect of the parabolic thin shell supported by a center fixation under explosive loading.Methods The shell was exposed in the impulsion acting field at first, then the deformation of the shell's surface was measured under different impulsive loading respectively, deformative feature and correlative relation were analyzed. The dynamic plastic response of the shell was analyzed with the similarity principle. Results The curves and relation of deformative quantities of the paraboloid shell were obtained. Conclusion The results can be used as guidance or experimental evidence in deformation effects analysis of radar antenna under impulsive loading. |
