Hydrogen‐Assisted Fracture of Iron‐Based Fe–Ni–Al Alloys

Advanced Engineering Materials, EarlyView.
Principal relations and fracture mechanisms of single‐phase and precipitate‐strengthened Fe–Ni–Al alloys subjected to prior electrochemical hydrogen charging are identified. The mechanisms of hydrogen effect on strength and microhardness are discussed, including hydrogen‐induced increase in microhardness and the role of hydrogen in fracture behavior ...

Cities without Skylines: Worldwide Building-Height Gaps and Their Implications [PDF]

, 2020
There is a large literature in the U.S. measuring the extent and stringency of land-use regulations in urban areas and how these regulations affect important outcomes such as housing prices and economic growth.

Detailed height mapping of trees and buildings (HiTAB) in Chicago and its implications to urban climate studies

Environmental Research Letters
The vertical dimensions of urban morphology, specifically the heights of trees and buildings, exert significant influence on wind flow fields in urban street canyons and the thermal environment of the urban fabric, subsequently affecting the microclimate,

Using shadows in high-resolution imagery to determine building height [PDF]

, 2011
This article presents a method for determining building height using shadows in remotely sensed data. The approach classifies building shadows based on their relative within-scene characteristics and spatial context, rules for which are determined ...

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A

Advanced Engineering Materials, EarlyView.
The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

High‐Temperature Nanoindentation of Metals: Assessing Thermal Drift, Frame Compliance, and Chemical Composition Effects on the Reported Mechanical Properties

Advanced Engineering Materials, EarlyView.
Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Wind interference between two high-rise building models: on the influence of shielding, channelling and buffeting on peak pressures [PDF]

, 2014
The influence of interference between two high-rise building models on the minimum peak pressures was investigated in an atmospheric boundary layer wind tunnel. Pressure measurements were performed on a square model with an aspect ratio of 1 to 4.
