Thermal elastic deformations of the planet Mercury [PDF]
Journal of Geophysical Research, 1972 The variation in solar heating due to the resonance rotation of Mercury produces periodic elastic deformations on the surface of the planet. The thermal stress and strain fields under Mercury's surface are calculated after certain simplifications. It is found that deformations penetrate to a greater depth than the variation of solar heating, and that ...

Dynamic Thermal Modeling of the Normal and Tumorous Breast under Elastic Deformation [PDF]
, 2008 To quantify the complex relationships between (1) the temperature, and temperature differences, on the surface of the breast as recorded by infrared thermal imaging and (2) the underlying physiological and pathological factors, we have developed a dynamic finite element method for comprehensive modeling of both the thermal and elastic properties of ...

Analyses of thermal and elastic deformations of honing head.
Journal of the Japan Society for Precision Engineering, 1990 This paper presents the deformation characteristics of honing head in order to improve the accuracy in honed hole diameter of in-process automatic sizing in honing. Thermal deformation by the warmed honing oil or by the heat generated during machining is experimentally examined.

Modelling and analysis of elastic and thermal deformations of a hybrid journal bearing
Tribology International, 2018 Abstract The continuous demand for higher power density leads to a very challenging operational environment for sliding bearings regarding pressures and deformations. Understanding of the deformation behavior of heavily loaded bearings becomes even more pronounced when modern hybrid multilayer designs are considered.
