  "textContent": "A turbomachine casing assembly 100;200;300 comprises a first casing element 110;210;310 locatable radially outward of one or more rotating aerofoil elements 130 of a turbomachine, a second casing element 120 located radially distal to the first casing element110;210;310. A void 134 is provided between a radially proximal face 114;214;314 of the first casing element 110;210;310 and a radially proximal face 124 of the second casing element 120, at the first end 112;212;312 of the first casing element 110;210;310. The first end 112;212;312 of the first casing element 110;210;310 is located against a corresponding first end 122 of the second casing element 120 by an energy absorbing element 140;142;230;340, with the first casing element 110;210;310;comprising a cantilever 180. The cantilever 180 is arranged in a region extending along the first casing element 110;210;310 from the first end 112;212;312;and having a pivot axis 182 at a mid portion thereof. Release of one of the rotating aerofoil elements 130 results in the element 130, or part thereof, impacting the first casing element 110;210;310 which results in the cantilever 180 bending into the void 134 provided between the first and second casing elements110;210;310,120. This enables the rotating aerofoil element 130 to be trapped within the casing assembly 100;200;300.",
