A two part probabilistic model for polycrystalline microstructures is described. The model utilizes a Poisson.Voronoi tessellation for the grain geometry and a vector random field model for the crystallographic orientation. The grain geometry mo[...]

In this paper the response of a bilinear oscillator subjected to pulse-type motions is revisited with dimensional analysis. Using Buckingham’s Πtheorem the number of variables in the response analysis is reduced from six (6) to four (4). When th[...]

This paper investigates the ’goodness’ of peak ground velocity as a dependable intensity measure for the earthquake shaking of civil structures. The paper stresses the importance of distinguishing between acceleration pulses and velocity pulses,[...]

The equation of motion of linear dynamic systems with viscoelastic memory is usually expressed in a integrodifferential form, and its numerical solution is computationally heavy. In two recent papers, the writers suggested that the system memory[...]

For a concrete beam resting on a bed of sand, an analytical solution technique is derived by which the mobility can be identified. To achieve realistic predictions, significant damping in the bed needs to be introduced. The modest damping of the[...]

Free vibration analysis of a through-width multidelaminated beam is performed in the present study. Multiple delaminations are assumed to spread from the top through the thickness direction of the beam. The natural frequencies of the multidelami[...]

When the identification of a linear system is carried out without deterministic input information the scaling constants that connect the eigensolution to the matrices of the physical system are not determined. One way to generate information to [...]

Compaction bands, a form of localized deformation found in field and laboratory specimens of high porosity rock, consist of planar zones of pure compressional deformation that form perpendicular to maximum compression. Experimentalists report co[...]
