Abstract: The dynamic equations for general helical springs are solved and classified according to the number of energy terms used to formulate them. Solutions of several sets of dynamic equations, each ...

Abstract: The complex form of the characteristic equation for the stress singularities of the order r λ–1 (0 < Re [λ]< 1 ) for the dissimilar anisotropic wedges is derived. Special attention is ...

Abstract: This paper discusses the rationality of the design force and damping reduction factors adopted by a few seismic design provisions for buildings with and without added passive energy dissipation systems. The issue will first ...

Abstract: The residual stresses in thin films are explained using elementary mechanics. In particular, the range of validity of the well-known Stoney’s formula is examined using a strength of materials ...

Abstract: The problem of two aligned orthotropic materials bonded perfectly along the interface with cracks embedded in either one or both of the materials while their directions being perpendicular to ...
