TL;DR: In this paper, the deformation associated with crystallographic slip and with the lattice rotation was determined in a copper micropillar oriented for single slip, in areas as small as 0.16×-0.16μm 2.

TL;DR: In this article, the effects of axial load variations on the seismic response of bridges isolated with friction pendulum systems (FPSs) are investigated, and a series of parametric time history non-linear analyses are performed for different bridge configurations.
Abstract: The effects of the axial load variations on the seismic response of bridges isolated with friction pendulum systems (FPS) are investigated. A series of parametric time history non-linear analyses are performed for different bridge configurations, defined after an extensive investigation on typical existing cases. The influence of both horizontal and vertical components of the ground motion is considered. The behaviour of the pier-isolator-deck system is predicted using two analytical models characterised by hysteretic loops sensitive or insensitive to axial force variations, in order to compare the different responses. Level of axial force, maximum displacements and induced bending moment are investigated, as well as shear and torsion demand, caused by different shear actions acting on the isolator devices. A comparison between demand and resistance capacity of the bridge piers is performed, in order to investigate possible non-conservative approaches in the current design methods and to raise controversi...

TL;DR: In this article, two nonlinear analysis methods are presented for finding the initial shape of suspension bridges under dead load, where the extended tangential stiffness matrices of the nonlinear frame element as well as the elastic catenary cable element are derived by adding unstrained element lengths to the unknown.

TL;DR: In this article, an advanced analysis method for three-dimensional semi-rigid steel frames accounting for three main nonlinear sources is presented, where the spread of plasticity over the cross section and along the member length is captured by monitoring the uniaxial stress-strain relation of each fiber on selected sections.

TL;DR: In this article, the bending moments are transmitted to the bone plates through the edges of curved apertures so that the built in transverse curvature of the plate is not crushed with resulting weakening.
Abstract: The present invention is a simple machine that permits the concentrated application of a bending moment to a stiff metallic bone plate. The present invention permits bends along three orthogonal torsional axes. The present invention can be scaled so that modest sized operators can bend the most stout bone plates. The bending moments are transmitted to the bone plates through the edges of curved apertures so that the built in transverse curvature of the plate is not crushed with resulting weakening of the plate. Finally, the apertures are rotated and angled to provide comfortable hand clearance and to permit efficient application of muscle force by the operator.
