Dynamic finite element analysis of micropolar elastic materials

Creator:: Kim, Jong-bum, 1960-
Abstract:: In granular or fibrous materials, in which the dimensions of the internal structure can be of the same order of magnitude as major flaws or holes, classical elasticity theory does not consistently provide accurate models of the large stress gradients that may develop. With the incorporation of additional rotational degrees...
Resource Type:: Dissertation

Micromechanics of heterogeneous materials under compressive loading

Creator:: Laird, George
Abstract:: In mining and mineral processing, compressive loading is often encountered during the comminution of ore bearing minerals and in the wear resistant materials used in the comminution circuit. A common thread joining many of the materials that are primarily used under compressive loading is the presence of a high modulus...

A photoelastic stress analysis of a beam under shear and compressive loads

Creator:: Bitting, Kenneth Robert
Abstract:: The determination of failure is complicated when a structural element is subjected to combined rather than simple stresses. This is especially true when the principle of superposition does not apply. For such cases, tests of the element under the expected loads are required to determine its failure criteria. In this...

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...

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...
