Friction stir processing (FSP) 2519-T87 aluminum plate results in enhanced ductility, 25% strain at fracture. However, the yield strength in the FSP zone drops to 175 MPa from �400 MPa. Actively cooling the plate during FSP increases the yield strength to 185 MPa and decreases ductility to 20% strain at fracture. Thick bending of a plate of the alloy was demonstrated after the surface was subje...

The paper discusses the numerical optimization design of anchoring end of prestressed cable at some hydropower station. There are two types of designing for the anchoring end, namely using square thick steel anchor bearing plate or using the roundtower anchor bearing plate. By the numerical calculation, the anchoring end using the round-tower anchor bearing plate can match the space and mechani...

To analyze the effect of stressed skin action of rigid plate covering on anti-collapse behavior of solar greenhouses under snow load, the numerical simulation on the overall collapse process of single skeleton structure and 6skeleton overall spatial structure with rigid plate covering were conducted on ANSYS. The collapse modes of solar greenhouses and snow load-displacement curves were obtaine...

This article presents a strategy for the fabrication of ordered microstructures using concepts of design inspired by molecular self-assembly and template-directed synthesis. The self-assembling components are 4-μm-thick hexagonal metal plates having sides 10 μm in length (“hexagons”), and each template consists of a 4-μm-thick circular metal plate surrounding a central cavity, the perimeter of ...

In vitro 3D culture could provide an important model of tissues in vivo, but assessing the effects of chemical compounds on cells in specific regions of 3D culture requires physical isolation of cells and thus currently relies mostly on delicate and low-throughput methods. This paper describes a technique ("cells-in-gels-in-paper", CiGiP) that permits rapid assembly of arrays of 3D cell culture...

It has been hypothesized that much of the crustal deformation attributed to the Laramide orogeny of the southwest North American Cordillera was caused by dynamic effects induced by the flat subduction of a large oceanic plateau that was embedded within the Farallon plate. Previous studies have identified within the North American mantle a seismic velocity anomaly that plausibly represents the r...

Foundations of structures which are subjected to uplift loading require anchoring systems to resist pullout loads. Such anchors can be broadly classified as gravity anchors, pile anchors and plate anchors. Plate anchors can be circular, square or strip in shape. The loading applied on plate anchors can be vertical, inclined or horizontal depending on the anchor orientation. In this study, vario...

Infinitesimal deformations of a homogeneous and isotropic thick elastic plate have been analyzed by using a meshless local Petrov– Galerkin (MLPG) method and a higher-order shear and normal deformable plate theory (HONSDPT). Radial basis functions (RBF) are employed for constructing trial solutions, while a spline function is used as the weight function over a local subdomain. The present metho...

The behavior of hollow-core columns composed reactive powder concrete (RPC) contained by a circular carbon fiber reinforced polymer (CFRP) tube is investigated numerically in this work. This research used hollow core column samples with an outside diameter 20.6 cm, interior 9cm, and height 80cm. These examples have been created utilizing 116 MPa concrete. Nine groupings specimens were created. ...
