Deformations of the Earth and the Thermal Core-Mantle Couplings
Journal of geomagnetism and geoelectricity, 1993 Zonal modes of mantle deformation may couple with the Earth's rotational motion. Increases of the LOD (slowing down of the Earth's rotational speed) suggest a coupling with increases of the vertical in the low latitude zone. This relation may be due to the angular momentum redistribution in the mantle associated with motions in the fluid core.

Study of Influence of Laser Cutting Sequence upon Thermal Deformation of a Base Sheet
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2007 In case that a lot of products were cut out from a wide base sheet by laser cutting, the sheet had been much deformed so that the error occurred in a height regulator. This paper deals with thermal deformation of a base sheet caused by laser cutting.

Periodic Thermal Deformation of Large Seal Ring
JSME international journal. Ser. C, Dynamics, control, robotics, design and manufacturing, 1994 Oil film seals of large diameter sometimes show long-period cyclic deformation of the floating seal ring whose rotation is constrained by a stopper pin. Cyclic change of deformation and oil film temperature may cause fatigue damage of the seal ring after long-term operation. We present a theory for the mechanisms of thermal deformation and its periodic
