In the paper, an influence of the amplitude of pulse loading and the thickness of susceptible parts taking over the pressure pulse on the absorber operation is investigated. The presented absorber consists of six truncated conical shells covered with a thin plate. Elements of the absorber are made of an isotropic material with a bilinear strain-stress curve. A nonlinear contact problem for the triangular loading pulse was solved with the ANSYS code.
