A mechanical shock absorbing apparatus is disclosed which includes a rheopectic polymeric material (18), a first structure (12) mechanically coupled to the rheopectic polymeric material (18) such that the first structure (12) is substantially immobilised relative to the rheopectic polymeric material (18) in at least one direction, a second structure (14) mechanically coupled to the rheopectic polymeric material (18) such that the second structure (14) is substantially immobilised relative to the rheopectic polymeric material (18) in the at least one direction, and compression means (22, 24) for applying a compression force to the rheopectic polymeric material (18) , the compression means (22, 24) being adjustable so as to adjust the compression force applied to the rheopectic polymeric material (18). The first structure (12), the second structure (14) and the compression means (22, 24) at least partially define an enclosure (16) for confining the rheopectic polymeric material (18) irrespective of the force applied to the rheopectic polymeric material (18) by the compression means (22, 24). In use, when a sudden load is applied to the first structure (12) or the second structure (14) in the at least one direction, the rheopectic polymeric material (18) is subjected to shear, and the rheopectic polymeric material (18) absorbs a proportion of said applied load dependent on the magnitude of the force applied by the compression means (22, 24). |
