Thermal stresses of a trimaterial medium in a nonuniform temperature field
Neibert, Michael Joseph
MetadataShow full item record
The objective of this investigation was to conduct a parametric study of the effect of a nonuniform temperature field on the system behavior of a trilayered medium. In particular, the resulting shear and normal stresses along the media interfaces are analyzed. A finite element model utilizing a recently developed element which provides for both axial and lateral displacement continuity is employed. First, the effect of the material properties, that is, Young's Modulus and coefficient of thermal expansion, is examined. Then, the effect of the geometric properties, that is, length and thickness dimensions of the midlayer, is analyzed. Finally, a study of the effect of a nonuniform temperature field on the trimaterial medium is conducted
