Control of peak stresses in tensile testing machine components subjected to shock loading

Creator:

Mitchell, Jack Alan

Abstract:

The mechanical properties of materials at cryogenic temperatures have been the subject of increasing interest during the past few years, although very little actual materials testing has been done at extremely low temperatures because of the high cost and low heat of vaporaization of liquid helium. Recently, the Department of...

Catastrophic propagation of ductile cracks in metallic foils

Creator:

Elliott, Leonard Thomas

Abstract:

The sudden failure of metal structures under load, which has been a design problem for many years, is characterized by a crack propagation rate which approaches the speed of sound in the material. These failures, which are often known as catastrophic fractures, may be divided into two types which depend...
