This paper presents a numerical investigation of the stress-strain state in a non-spherical shell subjected to pulsed loading. We examine the influence of the height-to-radius ratio of elliptical heads on the maximum stress values within explosion chamber shells. The dependence of the stress-strain state at the shell pole on the head height is also analyzed. It is demonstrated that employing elliptical heads with an optimal height-to-radius ratio mitigates stress concentration.
