Modeling of ultrasonic processes utilizing a generic software framework [PDF]
, 2017 Modeling of ultrasonic processes is typically characterized by a high degree of complexity. Different domains and size scales must be regarded, so that it is rather difficult to build up a single detailed overall model.

Shock-wave induced compressive stress on alumina ceramics by laser peening [PDF]
, 2019 Laser shock peening (LSP) of Al2O3 advanced ceramics is reported, showing underpinned physical mechanisms and potential benefits. It is known that localised plastic deformation can be induced in ceramics in the presence of a high hydrostatic pressure. It

High-precision determination of residual stress of polycrystalline coatings using optimised XRD-sin2ψ technique [PDF]
, 2010 The aim of the research is to optimise the XRD-sin2ψ technique in order to perform high precision measurement of surface residual stress. Residual stresses existing in most hard coatings have significant influence on the adhesion, mechanical properties

Effect of Ultrasonic Shot Peening on Shape Memory Alloy
Transactions of Japan Society of Spring Engineers, 2009 In order to overcome difficulties that have hindered precision casting of shape memory alloys, we made ingots created with self-propagating high temperature synthetic method (SHS) which eventually led us to the success of precision casting utilizing lost wax process.
