Abstract

Nettleton, M.A., 1979. Deformation of metallic components by explosive loads. Journal of Occupational Accidents, 2: 99-112.It is not always realised that the relationship between deformation of a ductile material and load depends on the rate of loading. The present note compares the behaviour of discs of aluminium, copper and mild steel, when loaded by a slowly applied hydraulic load, with that obtained with rapidly applied loads of duration greater than the response time of the disc. The latter were achieved by allowing a shock in air to reflect from the disc. The results indicate that the yield stress of the metal is influenced by the rate of loading and by its history and nature. The implications to the assessment of intensity of load, by measuring deformations produced in the positive phase of a blast-wave, are discussed.
