Influence of Residual Stresses on Geometric Parameters of Surface-Strengthened Beam

Authors: Radchenko V. P., Afanaseva O. S., Glebov V. E.

The сomprehensive study of the formation of residual stresses and plastic deformations in prismatic samples of the EP742 alloy after ultrasonic hardening and their influence on the geometric parameters of the beam was conducted. Phenomenological model for the reconstruction of residual stress fields is proposed, and the verification of its adequacy to experimental data with four hardening modes is performed. The correspondence of the calculated and experimental data is observed.

Determination of Attaching Parameters of Inhomogeneous Beams in the Presence of Damping

Authors: Vatulyan A. O., Vasilev L. V.

Characterization of solids by additional data on displacements amplitudes or resonance frequencies have been increasingly attracting attention of researchers in recent years. Among the tasks of this type, the problems associated with definition of parameters describing boundary conditions and characterizing an interaction of the body studied with the surrounding bodies are of particular interest. In this paper, we investigate the problem of determining the parameters of the boundary conditions in a beam.
