We model elastic waves in bearing raceways to detect defects and friction. By treating raceways as hollow cylinders, we derive 4×4 systems for vibrational modes, enabling forward and inverse problem solving. Using roller count and speed as priors reduces sensor requirements. Examples show recovery of contact traction and detection of elastic emissions.
A large variety of engineering and biological materials have a non-zero internal stress distribution, even in the absence of applied forces. These stresses can arise from thermal expansion or volumetric growth, for example, in the production of the …
Mechanical stress in tissue is important but hard to measure. The angled shear wave identity (ASWI) estimates stress from shear-wave speeds without needing a constitutive model. This work extends ASWI to viscous and anisotropic tissues, deriving the …
